[Phytoplankton dilution experiments] - Division rates, grazing rates, and accumulation rates from phytoplankton dilution experiments conducted on cruises aboard the R/V Robert Gordon Sproul along the Southern California coast during July and August 2023 (Postdoctoral Fellowship: OCE-PRF: Smoke on the water: the impacts of wildfire ash deposition on surface ocean biology)

These data include division rates, grazing rates, and accumulation rates from dilution experiments conducted on cruises aboard the R/V Robert Gordon Sproul (SP2319, SP2320) between dates 2023-07-28 and 2023-08-19 along the Southern California coast. Dilution experiments were used to assess phytoplankton growth and microzooplankton grazing rates.

Deposition of wildfire ash on the ocean can fertilize microbial production but also has the potential to inhibit microbial growth due to heavy metal toxicity. The data collected from these field experiments can contribute to elevating understanding of wildfire-driven material transfer from the terrestrial system to the ocean and its impact on carbon and energy flow in marine food webs. These data were collected by Dr. Nicholas Baetge, Dr. Jason Graff, Dr. Allen Milligan, Brian Ver Wey, and Parker Hansen of Oregon State University.

[Phytoplankton Growth Acclimation] - Growth rates and equivalent spherical diameters of Heterosigma akashiwo after temperature transition (Quantifying Temperature Dependence In Growth & Grazing Rates of Planktonic Herbivores)

Quantifying phytoplankton growth as a function of environmental conditions such as temperature is critical for understanding and predicting production in the ocean. Typically, thermal response is described as the steady state growth rates under static conditions. However, here, with a clonal culture of Heterosigma akashiwo, temperature was manipulated in the laboratory with the goal of describing how growth rates may change over time through the acclimation process. Growth rates and equivalent spherical diameter of Heterosigma akashiwo after temperature transition are reported.

[Phytoplankton size over temperature range] - Equivalent spherical diameter of Heterosigma akashiwo grown at different temperatures (Quantifying Temperature Dependence In Growth & Grazing Rates of Planktonic Herbivores)

A key component of the effects of temperature on growth and production of phytoplankton is not only through changes in numerical abundance, but also biomass and proxies for biomass such as biovolume. To understand how temperature affected size and biovolumetric growth, repeated measurements of the mean size feature, equivalent spherical diameter (ESD), were recorded for each experimental replicate culture of Heterosigma akashiwo across a broad range of temperature treatments. These data were collected as part of the experiment designed to study the effect of changing temperature on phytoplankton growth rates.

[phytoplankton taxonomy] - Time-Series of Phytoplankton Taxonomy and Density collected by the CARIACO Ocean Time-Series Project from November 1995 to January 2017 (CARIACO Ocean Time-Series Program)

The CARIACO Ocean Time-Series Program (formerly known as CArbon Retention In A Colored Ocean) started on November 1995 (CAR-001) and ended on January 2017 (CAR-232). Monthly cruises were conducted to the CARIACO station (10.50\u00b0 N, 64.67\u00b0 W) onboard the R/V Hermano Gin\u00e9s of the Fundaci\u00f3n La Salle de Ciencias Naturales de Venezuela. The program studied the relationship between surface primary production, physical forcing variables like the wind, and the settling flux of particulate carbon in the Cariaco Basin. This depression, located on the continental shelf of Venezuela, shows marked seasonal and interannual variation in hydrographic properties and primary production (carbon fixation rates by photosynthesis of planktonic algae).\r\n\r\nOne of the monthly measurements taken by the program was water sampling at different depths for phytoplankton taxonomy (occurrence and density). Those water samples were collected with Niskin bottles during the first CTD Cast of the morning at 1, 7, 25, 35, 75, and 100 m depth. Phytoplankton taxonomy and density was determined at each depth at the level of species or genera. Values of zero are real and denote that a specific species was not found at that cruise/depth.

Picoeukaryotic phytoplankton observations from available public repositories and primary sources. Picoeukaryotic phytoplankton are defined as red fluorescent cells larger than Prochlorococcus and less than 2-3 \u00b5m in cell diameter. We only considered cell counts by flow cytometry. Samples covered a latitudinal range from 71.4\u02daN to 66.1\u02daS up to 400 m depth. Ancillary temperature and nitrate records were available for all but 2,334 and 6,530 observations, respectively, which we complemented with 1\u00b0 monthly depth-dependent averages from the World Ocean Atlas (www.nodc.noaa.gov). To avoid analytical issues with detection limits, we imposed a minimum nitrate concentration of 0.01 \u03bcM. We calculated surface PAR (8 d averaged, 0.047\u00b0 grid cell) using SeaWiFS and MODIS observations. Downward PAR was estimated using the attenuation coefficient K\u2084\u2089\u2080 from SeaWiFS and MODIS (https://oceancolor.gsfc.nasa.gov) and corrected for chlorophyll a\u00b3\u2070, and a minimum of 10\u207b\u00b3 E/m\u00b2d was imposed.

These data represent measurements of individual sinking particle types—specifically fecal aggregates, phytodetrital aggregates, euphausiid and other crustacean fecal pellets, and debris—collected from the Bermuda Atlantic Time-series Study (BATS) site. Sampling occurred during six time points: July 2021, November 2021, March 2022, July 2022, November 2022, and March 2023. Particle interceptor traps (PITs) were deployed at depths of 150 m, 200 m, and 300 m, each equipped with three gel-filled collection cups to preserve particle morphology. The collected particles were analyzed to quantify area and biovolume for each particle type, contributing to a better understanding of the composition and flux of sinking material in the mesopelagic zone.
The data were collected aboard the R/V Atlantic Explorer through the collaborative efforts of the laboratories of Dr. Susanne Neuer, Dr. Amy Maas, and Dr. Leocadio Blanco-Bercial, affiliated with Arizona State University and the Bermuda Institute of Ocean Sciences. These measurements support research into particle-mediated carbon flux and the biological carbon pump, and are intended for use by scientists studying marine biogeochemistry, particle dynamics, and oceanic carbon cycling.

[Planktic foraminifera assemblages MAZ-1E-04] - Planktic foraminifera assemblages in the eastern Pacific during the last deglaciation determined from core MAZ-1E-04 collected on cruise MAZ-I aboard the R/V El Puma in April 2015 (Glacial-Interglacial Changes in Oxygen Minimum Zones Using Deep-Dwelling, Low-Oxygen Planktic Foraminifera)

The structure and drivers of oxygen minimum zone (OMZ) evolution in the Eastern Tropical North Pacific (ETNP) are investigated from ~20.7-10 ka using planktic foraminiferal assemblages alongside multiple other proxies from core MAZ-1E-04 (22°54.29'N, 106°54.59'W; 1463 m depth). Understanding how OMZ vertical structure changed during past glacial/interglacial cycles will help elucidate the drivers and patterns of OMZ expansion/contraction on longer timescales.

Planktic foraminifera assemblage counts from core MAZ-1E-04, collected on cruise MAZ-I aboard the R/V El Puma in April 2015, are used here to explore any composition shifts driven by environmental changes. Universidad Nacional Autónoma de México financed ship time and M. Alejandro Rodríguez Ramírez directed the oceanographic campaign to retrieve the core.

[Plate Rates Bulk TN362] - Peptidase and glucosidase activities from bulk water incubations from waters taken aboard the R/V Thomas G. Thompson in the Southern Indian Ocean during the research cruise TN362 in November and December, 2018 (A mechanistic microbial underpinning for the size-reactivity continuum of dissolved organic carbon degradation)

Marine dissolved organic matter (DOM) is one of the largest actively-cycling reservoirs of organic carbon on the planet, and thus a major component of the global carbon cycle. The existence of a size-reactivity continuum of DOM - observations and measurements showing that HMW (high-molecular-weight) DOM tends to be younger and more reactive than lower MW (molecular-weight) DOM - has been demonstrated in laboratory and field investigations in different parts of the ocean. A mechanistic explanation for the greater reactivity of HMW DOM has been lacking, however. Here we investigated the potential of seawater microbial communities from different water masses to hydrolyze six high-molecular-weight polysaccharides (arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan).

This dataset includes the measurement of peptidase and glucosidase activities from samples taken from bulk water incubations from various stations and depths aboard the R/V Thomas G. Thompson in the Southern Indian Ocean during the research cruise TN362 in November and December, 2018.

[PMP counts in sponges and seawater from Panama] - Potential microplastic counts of 6 common Caribbean spong species collected June 21, 2019 in Bocas del Toro, Panama (Collaborative Research: Investigations into microbially mediated ecological diversification in sponges)

Microplastics (MP) are now considered ubiquitous across global aquatic environments. The ingestion of MP by fish and other marine vertebrates is well studied, but the ingestion of MP by marine invertebrates is not. Sponges (Phylum Porifera) are particularly understudied when it comes to MP ingestion, even though they are widely distributed across benthic habitats, can process large volumes of seawater, and can retain small particles within their water filtration systems. This study examines the presence of potential MP (PMP) in wild marine sponges and seawater collected in Bocas del Toro, Panamá. Subsurface seawater and tissue from six common Caribbean sponge species was collected in Saigon Bay, a heavily impacted, shallow-water coral reef. Seawater samples were filtered onto glass fiber filters to retain any PMP present and sponge tissue was digested with bleach, heated and filtered. Filters were examined using fluorescence microscopy to quantify PMP. An average of 107 ± 25 PMP L–1 was detected in seawater from Saigon Bay with particles ranging in size between 10 μm and ~3,000 μm. The number of PMP found in sponge tissue ranged between 6 ± 4 and 169 ± 71 PMP g–1 of dry tissue. Most particles found in sponge samples were very small (10–20 μm), but fibers greater than 5,000 μm were detected. Our results indicate that PMP exists within the tissues of the sponges we studied, but future studies should confirm the presence of MP in sponges using chemical analysis. Most importantly, the discrepancy between low levels of PMP in our sponge samples and high levels in the surrounding seawater highlights the potential for sponges to resist and/or egest MP. Finally, we provide a critical evaluation of our methods to improve their use in future MP work with benthic marine organisms.

Yet, we lack a clear understanding of the molecular toolkit enabling acclimatization to environmental extremes, and how life-long exposure to pCO2 variability influences biomineralization. We examined the gene expression responses and micro-skeletal characteristics of Pocillopora damicornis originating from the reef flat and reef slope of Heron Island, southern Great Barrier Reef. The reef flat (454 ± 3.0) and reef slope (418 ± 1.9) had similar mean seawater pCO2 (µatm; mean ± SE), but the reef flat experienced twice the mean daily pCO2 amplitude (range of 797v. 399 µatm day-1, respectively). A controlled mesocosm experiment was conducted over eight weeks, exposing P. damicornis from the reef slope and reef flat to stable (218±9) or variable (911±31) diel pCO2 fluctuations (µatm; mean ± SE).

This dataset includes the data and analyses for the overall skeletal micromorphological analyses of P. damicornis, including the origin reef environment, treatment, colony ID, feature of interest, image magnification, image name, observer, replicate, corallite diameter, distance between corallites, area, perimeter, and circularity.

[Pocillopora species ID from Recharge project] - Differential effects of nutrients and consumer pressure on sympatric cryptic coral species (Pocillopora spp.) in Moorea, French Polynesia sampled in November 2021. (Collaborative research: Coral community resilience: testing the role of hidden diversity in pocilloporid corals at Moorea)

Cryptic species (evolutionarily distinct lineages that do not align with morphologically defined species) are being increasingly discovered but are poorly integrated into ecological theory. In particular, we still lack a useful understanding of if and how cryptic species differ in ways that affect community recovery from disturbances and responses to anthropogenic stressors, such as the removal of consumers and pollution from nutrients.

On coral reefs, nutrient pollution increases the growth of macroalgae that displaces corals. Reductions in herbivorous fishes reduce the suppression of macroalgae, while reductions in coralivorous fishes reduce predation on corals. An unresolved question is if and how cryptic coral species respond differently to these impacts, thereby differing in their ability to influence coral community dynamics and maintain coral dominance. Therefore, we assessed how the response of cryptic Pocillopora species over a period of three years following a simulated disturbance from a cyclone depended on the experimental reduction of fish consumer pressure and nutrient addition. After three years, five morphologically cryptic, but genetically distinct, Pocillopora species recruited to the reef. However, recruitment was dominated by two species: P. tuahiniensis (46%) and P. meandrina (43%).

Under ambient conditions, recruitment of P. tuahiniensis and P. meandrina was similar, but experimentally reducing consumer pressure increased recruitment of P. tuahiniensis by up to 73% and reduced recruitment of P. meandrina by up to 49%. In both species, nutrient enrichment increased recruitment and colony growth rates equally, but colonies of P. tuahiniensis grew faster, and were up to 25% larger after three years, than those of P. meandrina, and growth was unaffected by reduced consumer pressure. Predation by excavating corallivorous fish was higher for P. meandrina than for P. tuahiniensis, especially under nutrient enrichment. In contrast, polyp extension (an indicator of elevated heterotrophic feeding as well as susceptibility and attractiveness to corallivores) was lower for P. meandrina than for P. tuahiniensis, especially under low to medium consumer pressure. Overall, we uncovered ecological differences in the response of morphologically cryptic foundation species to two pervasive stressors on coral reefs.

Our results demonstrate how cryptic species respond differently to key anthropogenic stressors, which may contribute to response diversity that can support ecological resilience or increase extinction risk.

[Polysaccharide Hydrolase Activities under Varying Hydrostatic Pressures near Helsingor in 2023] - Polysaccharide Hydrolase Activities in Danish Coastal Seawater and Sediments under Varying Hydrostatic Pressures on samples collected in September 2023 (Collaborative Research: Pressure effects on microbially-catalyzed organic matter degradation in the deep ocean)

The potential of the seawater or sedimentary microbial community to hydrolyze seven high-molecular-weight polysaccharides (arabinogalactan, chondroitin sulfate, fucoidan, laminarin, mannan, pullulan, and xylan) was investigated in a coastal station off the coast of Helsingor, Denmark. This investigation was part of the larger project to understand pressure effects on enzymatic activity. These samples were collected in September 2023 at a coastal station off the coast of Helsingor, Denmark, at a depth of 20 meters.

Through our collaboration with the Danish Center for Hadal Research, we were able to use pressurization systems and in situ specialized equipment to investigate the effects of pressures characteristic of bathy- and abyssopelagic depths on microbial communities and their extracellular enzymes in the open North Atlantic Ocean.

This dataset contains metadata on sample collection, environmental conditions, sample types and treatments, incubation conditions, substrate types, and kill-corrected enzymatic hydrolysis rates across timepoints.

[Polysaccharide hydrolysis rates from Arctic fjord Kongsfjorden April 2018] - Measurement of polysaccharide hydrolysis rates from water samples collected from the Arctic fjord Kongsfjorden near Ny-Ålesund, Svalbard, during April 2018 (A mechanistic microbial underpinning for the size-reactivity continuum of dissolved organic carbon degradation)

Marine dissolved organic matter (DOM) is one of the largest actively-cycling reservoirs of organic carbon on the planet, and thus a major component of the global carbon cycle. The existence of a size-reactivity continuum of DOM - observations and measurements showing that high molecular weight (HMW) DOM tends to be younger and more reactive than lower MW DOM - has been demonstrated in laboratory and field investigations in different parts of the ocean. A mechanistic explanation for the greater reactivity of HMW DOM has been lacking, however. Here we investigated the potential of seawater microbial communities from different water masses to hydrolyze six high-molecular-weight polysaccharides: arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan.

[pooled random sites (PRS)] - Coral community structure at pooled random sites between Cabritte Horn and White Point in St. John before and after five hurricanes from 1988–2017 (RUI-LTREB Renewal: Three decades of coral reef community dynamics in St. John, USVI: 2014-2019)

These files contain data that support an analysis of the effects of two major hurricanes on coral reefs that have been extensively studied for more than three decades. Major tropical storms are destructive phenomena with large effects on the community dynamics of multiple biomes. On coral reefs, their impacts have been described for decades, leading to the expectation that future storms should have effects similar to those recorded in the past. This expectation relies on the assumption that storm intensities will remain unchanged, and the impacted coral reef communities are similar to those of the recent past; neither assumption is correct. These data support a study quantifying the effects of two category five hurricanes on the reefs of St. John, US Virgin Islands, where 31 y of time-series analyses reveal chronic coral mortality, increasing macroalgal abundance, and five major hurricanes that caused acute coral mortality. Contextualized by these trends, the effects of the most recent storms, Hurricanes Irma and Maria (September 2017), on coral cover were modest. While mean absolute coral cover declined 1\u20134% depending on site, these effects were not statistically discernable. Following decades of increasing abundance of macroalgae, this functional group responded to the  recent hurricanes with large increases in abundance on both absolute and relative scales. Decades of chronic mortality have changed the coral assemblages of St. John to create degraded communities that are resistant to severe storms.

[Population genomics datasets of invasive and native populations of a red seaweed] - Red seaweed Gracilaria vermiculophylla population genomics (SNP genotype likelihoods) from collections of populations in Asia North America and Europe in 2014 and 2015 (Detecting genetic adaptation during marine invasions)

We describe the relative influence of bottlenecks, clonality, and population expansion in determining genomic variability of the widespread red macroalga Gracilaria vermiculophylla. Its introduction from mainland Japan to the estuaries of North America and Europe coincided with shifts from predominantly sexual to partially clonal reproduction and rapid adaptive evolution. We surveyed 62,285 single nucleotide polymorphisms (SNPs) for 351 individuals from 35 populations, aligned to 24 chromosome-length scaffolds that we publish for the first time.

This dataset includes metadata, methods, links to published code and processed data used to generate figures for the results publication Flanagan et al.

[Porewater DOM NMR spectra] - 1H NMR spectra of whole porewater DOM in California margin sediments from 2020 (Sikuliaq) (Collaborative Research: Peptide Deamination as a Source of Refractory Dissolved Organic Matter in Marine Sediments)

1H NMR spectra of whole dissolved organic matter (DOM) samples are reported for StaD and StaK, located in the upper slope offshore central California. Sediment and porewater sampling were done in Dec 2020 onboard the R/V Sikuliaq. Sediment samples were retrieved using multi-cores and gravity cores operated by the Oregon State University Marine Rock and Sediment Sampling Group. Porewater samples were extracted from the sediment within hours of core retrieval in a refrigerated van. Rhizon samplers were used to collect porewater from multicores, whereas centrifugation was used for porewater collection from gravity cores. Upon collection, porewater samples were immediately poisoned with mercuric chloride and flame-sealed in glass ampules under a stream of ultra-high-purity nitrogen gas and refrigerated until analysis. Reported here are 1H NMR spectra of whole DOM samples, UV-irradiated deionized water blanks collected on the ship, and UV-irradiated deionized water pulled through Rhizon samplers (all 0.2-micron filtered).

[Porites PLD experiment] - Results of a lab experiment to determine the range of pelagic larval duration in massive Porites larvae in Palau in 2023 (Collaborative Research: How do selection, plasticity, and dispersal interact to determine coral success in warmer and more variable environments?)

The period of time that larvae spend in the water column, the pelagic larval duration (PLD), has a profound impact on dispersal distance. Characterizing variations in PLD across a population is critical for refined estimates of dispersal, yet this work is rarely done. We conducted an experiment to characterize the PLD of massive Porites larvae in April 2023. Adult massive Porites corals were collected from six sites in Palau immediately prior to their spawning, around the full moon. Collected corals were held in individual plastic containers in ambient unfiltered flow-through seawater tanks at the Palau International Coral Reef Center (PICRC).  Larvae from two bulk crosses were pooled for this experiment. Each cross included sperm from 3 males and eggs from one female . Three-dpf larvae (n=20 individuals) were added to clear plastic culture dishes (~200 mL) with ambient seawater (ASW) at three different filtrations: unfiltered, 5 μm filtered, or 0.5 μm filtered (n=10 per treatment). No additional settlement cues were provided. Culture dishes were maintained in flow-through ASW tanks at PICRC, and ~80% water changes were conducted every 2 days. Temperature and light experienced by larvae during the experiment were recorded using Hobo pendant loggers in an identical culture dish in the same seawater tank. Immediately prior to water changes, all larvae and settlers in each culture dish were counted. Settlement was defined as a larva attaching itself to the bottom of the dish, remaining attached after mechanical disturbance (i.e., gently shaking the dish), and visually beginning to undergo metamorphosis.

[Porites post-settlement experiment] - Results of an experiment on post-settlement survival for Porites corals in Palau (Collaborative Research: How do selection, plasticity, and dispersal interact to determine coral success in warmer and more variable environments?)

The early life-history stages of marine invertebrates, including corals, are subject to high mortality. Numerous environmental and biological factors serve as bottlenecks, restricting recruitment and connectivity of populations. We conducted a lab experiment to determine the influence of temperature and light on post-settlement mortality of massive Porites corals in April 2023. Adult massive Porites corals were collected from six sites in Palau immediately prior to their spawning season. Collected corals were held in individual plastic containers (4.2 L; 17 x 13 x 19 cm) in ambient unfiltered flow-through seawater tanks at the Palau International Coral Reef Center (PICRC). Three days post fertilization, larvae were settled on glass microscope slides with crushed crustose coralline algae used as a settlement cue.  Slides were randomly distributed among two temperature treatments (30° C, 33° C) and two light levels (ambient, high) in a 2-way crossed design. Immediately after settlement and every two days throughout the experiment, slides were photographed individually using a Nikon D850 camera with a macro lens. Living settlers were counted in each image to track settler survival over time. Temperature and light level in each treatment were logged using Hobo pendants (Onset, Wareham, USA).

[Post-hurricane Sponge Volume] - Sponge volume from repeated surveys in St. Thomas, U.S. Virgin Islands, before and after the 2017 hurricane season (RAPID: Collaborative Research: Sponge resilience in the face of multiple stressors)

Prior to the 2017 hurricanes, six shallow (8-15 meter depth) reef sites had been selected from the Virgin Islands Territorial Coral Reef Monitoring Program's (TCRMP) permanent monitoring sites to study variation in sponge communities - Black Point (BP), Coculus Rock (CR), and Magens Bay (MB), which are in embayments with heavily developed watersheds. Buck Island (BI) and Savana Island (SI) are located near undeveloped offshore cays. Botany Bay (BB) is a nearshore site in a bay with a low level of watershed development.

This dataset represents sponge volume from these repeated surveys before and after the 2017 hurricane season. We used three randomly selected transects out of the six permanently established 10-meter TCRMP transects at each site. The same three transects at each site were re-surveyed repeatedly in August 2016 (pre-hurricanes), December 2017 (10 weeks post-hurricanes), March 2018 (24 weeks post-hurricanes), November 2018 (61 weeks post-hurricanes), and July 2019 (93 weeks post-hurricanes).

[Pre-experiment Urchin Barren Characterization] -  (CAREER: Energy fluxes and community stability in a dynamic, high-latitude kelp ecosystem)

Before experimental manipulation with caged Pycnopodia helianthoides presence, we characterized ambient density, gonad index, and size distributions of urchin communities ( Strongylocentrotus droebachiensis and Mesocentrotus franciscanus) in three replicate urchin barrens in Sitka Sound, AK (57°2'1"N 135°15'51"W) from February 11-20, 2023. Via SCUBA we conducted swath surveys where grazers were identified, counted, measured (test diameter), and randomly collected for gonad dissections. These surveys serve as a baseline to describe these sites as true barrens and to compare experimental results to.

[Predation Rate] - Predation rates by Pisaster ochraceus on Mytilus californianus along the Oregon and Northern California rocky intertidal coastline from 1999 to 2023 (RAPID: Testing the rocky intertidal community consequences of the decimation of purple sea star populations along the Oregon coast by sea star wasting disease)

This dataset contains time-series measurements of mussel (Mytilus californianus) survival and experimental predation rates by the sea star Pisaster ochraceus from rocky intertidal sites along the North American west coast from 1999 to 2023.

Study/Experiment abstract:

Mass mortality from disease epidemics can challenge the resistance and resilience of populations and communities. Assessing the impacts of such events and their consequences is crucially dependent on long-term datasets. In 2013-16, sea star wasting disease (SSWD) caused population-wide crashes of the archetypal keystone species, the sea star Pisaster ochraceus, along the North American west coast. We used a long-term dataset to assess how predation rates by Pisaster on Mytilus californianus varied over a 16-year time series (2007-2023) of annual predation rate at 7 sites. As expected, SSWD drove predation rates to near-zero. This persisted for 3-8 years depending on site, and as of 2024, predation rates at two sites remained unrecovered.

[Predator Induced and Non-Induced Eastern Oyster Shell Hardness] - Oyster shell hardness from study of eastern oysters (Crassostrea virginica) grown in a nursery with or without exposure to chemical cues from blue crabs (Collaborative Research: Keystone chemicals: Identifying general and universal molecules of fear)

This dataset is associated with the study "Eastern oysters alter inducible defense mechanism of shell strengthening with age". This study tested which mechanism, hardness or thickness, juvenile eastern oysters use to strengthen their shells in response to chemical cues from predators. Data was collected from eastern oysters, Crassostrea virginica, grown in a nursery in Dauphin Island, Alabama, USA with or without exposure to chemical cues from blue crabs, Callinectes sapidus. Two age groups (four-week and eight-week-old post-settlement) of juveniles were included in this study. Oyster shells were tested for shell hardness within both shell layers. Measurements include the Vickers hardness values of foliated and prismatic oyster shell layers, as well as the number and length of cracks resulting from hardness tests.
