[Species Sizes] - Lengths of organisms recorded during emergent and rapid emergent surveys conducted in the subtidal zone of northern California, Sonoma and Mendocino counties, from 1999 to 2023 (Collaborative Research: The effects of marine heatwaves on reproduction, larval transport and recruitment in sea urchin metapopulations)

The Kelp Forest Monitoring data record span surveys across 24 years from 1999 through 2023 at 20 locations on the Sonoma-Mendocino Coast, Northern California. Years without data, inclusive: 2002, 2020, 2021. These surveys are ongoing and are conducted by the California Department of Fish and Wildlife dive team with participation from dive program partners at UC Davis, UC Santa Cruz, Cal Poly Humboldt, Sonoma State and other dive programs and volunteers. Not all sites were surveyed in all years. Surveys prior to 2003 were not conducted by the same teams or with the same methods except that all surveys were done using Scuba along 30-meter x 2-meter transects randomly placed in the subtidal zone in rocky habitats dominated by bull kelp, Nereocystis luetkeana, forests. These randomly placed band transect surveys were stratified by depth (A=0-15, B=16-30, C=31-45, D=46-60 ft) as we know sea urchin and abalone populations differ by depth.

Organisms along the transect were identified and measured on the longest axis to the nearest millimeter by the divers. Sea urchin and abalone species were identified and measured for every dive transect. However, data on associated species differed depending on resources, the year, and the focus of the studies in response to ecosystem conditions.

[Specific Dynamic Action of larval grunion - Experiment 1] - Differences in mean oxygen consumption of fed and unfed larvae used to understand the metabolic cost of digestion, Specific Dynamic Action (SDA), under ocean acidification and warming treatments - Experiment 1 (RUI: Evaluating selection via ocean acidification and evolutionary responses of two coastal fishes)

These data include the differences in mean oxygen consumption of fed and unfed larvae used to understand the metabolic cost of digestion, Specific Dynamic Action (SDA), under ocean acidification and warming treatments. Data was collected in the summers of 2021 and 2022 using a microplate reader system that uses optical fluorescence to measure dissolved oxygen concentrations in water. Knowing the energetic cost of digestion under future climate change is important as studies, particularly on larval fish, begin to investigate how energy budgets will change. These data help us to understand an important part of daily metabolic costs and how that cost might change under ocean acidification and warming. Data were collected by Emma Siegfried and Dr. Darren Johnson at California State University, Long Beach. These data are from Experiment 1 and they contain delta VO2 values to describe the SDA curve for a single feeding at a single temperature (20 degrees Celsius).

[Sponge Density, Morphology, and Assemblages] - Sponge Density, Morphology, and Assemblages 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 density, morphology, and assemblages 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).

(RAPID: Too hot to hold: Effects of unseasonable warming on the Azores nekton community and its keystone taxon)

ITAGs were used to measure squid movement dynamics. The sensor package was small (12.5 × 2.6 × 2.7 cm) and was affixed using surgical sutures . Additionally, ITAGs were neutrally buoyant, hydrodynamic, and focal tagged squid exhibited normal swimming and schooling behaviors with other conspecifics. ITAGs contain an inertial measurement unit (IMU) which measures acceleration, magnetic field strength, and angular velocity. These tags were used to measure the swimming behavior or free-ranging animals in the Azores region in November 2021, and May 2023. These data provide movement intensities, behaviors, and allow us to measure the environment including light, temperature, and the animal's depth. Here, we are submitting the tag data from the free-ranging animals in matrix form (.csv).

These data set contain results from trials used to measured predation rates by fish across time and sites showing  a temperature gradient in San Cristobal, Galapagos. We used the squidpop protocol, an assay based in setting 25 stakes with squid bait for one hour in the reefs. Afterward we count how many bait were eaten to have a measure of predation rate.  We did this on 15 sites. In 6 of this sites we conducted the assay every two months for 15 months.  Measuring the relationship between temperature and predation on reefs will allow us to understand better the role of temperature on moderating predation on marine communities.

[SR2114 Fish larvae isotope data] - Carbon and nitrogen isotope data from zooplankton and fish larvae collected on the SR2114 expedition in the Eastern Tropical North Pacific aboard the R/V Sally Ride from December 2021 to January 2022 (Collaborative Research: Multiyear autonomous measurement of N-loss in the ETNP ODZ)

This dataset includes carbon and nitrogen isotope data from zooplankton and fish larvae collected on the SR2114 expedition onboard the RV Sally Ride from December 2021 to January 2022. Samples were collected using a MOCNESS (Multiple Opening-Closing Net and Environmental Sensing) system. The vertical sampling strategy followed five specific oxypleths (referred to as sampling levels) using horizontal tows. The zooplankton samples were preserved in ethanol 95%. The stable isotope ratios of carbon (13C/12C) and nitrogen (15N/14N) were measured on 39 samples of zooplankton, 44 samples of fish larvae, and 8 samples of fish adults. Carbon and nitrogen isotope ratios were measured at the Boston University Stable Isotope Laboratory using a GV Instruments IsoPrime isotope ratio mass spectrometer coupled with an elemental analyzer. The results were compared to international standards (Pee Dee Belemnite for 13C and atmospheric nitrogen for 15N) and presented as delta notation. This methodology was followed to gather information on the trophic structure of the ecosystem and its ontogenic changes during early fish development.

[SRA accessions from Chesapeake Bay sediment samples 2017-2018] - SRA accession and collection metadata for sediments samples collected at two Chesapeake Bay stations from Mar 2017 to Aug 2018 (Collaborative Research: Probing the Metabolic and Electrical Interactions of Cable Bacteria in Anoxic Sediments)

To examine the seasonality of sulfur oxidizers in surface sediments in seasonality oxygen stressed sediments of the Chesapeake Bay, surface sediments (0-0.5 cm depth) were collected on 10 occasions spanning all seasons over the course of two years by gravity coring at a pair of stations with differing summer bottom water oxygen concentrations. Samples were collected from March of 2017 to August of 2018. One station was located in the central channel which experiences severe summer hypoxia (CB4.3C) and one station was located on an adjacent shoal where bottom waters are better ventilated (CB4.3W; station names associated with Chesapeake Bay Water Quality Monitoring Program). At both stations, the waters are mesohaline and the sediments are fine grained. The study was designed to enable a description of the seasonality of benthic microbial communities at paired locations with contrasting degrees of bioturbation.
This dataset includes collection metadata, Sequence Read Archive (SRA) and BioSample accessions under BioProject PRJNA613483 at The National Center for Biotechnology Information and are associated with BCO-DMO datasets, all listed under related datasets.

[SRA archive of Magallana gigas] - NCBI accession numbers and related metadata for an SRA archive of the Pacific oyster, Magallana gigas (The genetic legacy of an Asian oyster introduction and its disease-causing parasite)

The massive geographic expansion of terrestrial plant crops, livestock, and marine aquacultured species during the 19th and 20th centuries provided local economic benefits, stabilized food demands, and altered local ecosystems. The invasion history of these translocations remains uncertain for most species, limiting our understanding of their future adaptive potential and historical roles as vectors for co-invaded species. We provide a framework for filling this gap in invasion biology using the widely transplanted Pacific oyster (Magallana gigas) as a case study. A two-dimensional summary of population-level variation in single nucleotide polymorphisms (SNPs) in native Japan reflected the geographical map of Japan and allowed identification of the source regions for the worldwide expansion. Pacific oysters proliferate in non-native areas with environmental temperatures similar to those areas where native lineages evolved.

The herbivorus green sea urchin (Lytechinus variegatus) was surveyed across the southern part of St. Joseph Bay at 16 sites spaced approximately 1 nautical mile apart. Initial surveys were performed in May 2016 as part of a prior study of seagrass coverage, reproduction, and herbivore intensity. Using RAPID funds, the same survey was conducted in August 2019, 11 months after Hurricane Michael, an extremely powerful category 5 tropical cyclone, made landfall nearby with devastating effects. Densities were recorded by snorkelers in 5 replicate, haphazardly thrown 0.25-m2 quadrats at each site.

Comparing pre- and post-hurricane urchin densities allows for estimates of how Hurricane Michael's passage impacted resident urchin densities. These data were collected by Dorothy Byron and Alexandra Rodriguez of the Dauphin Island Sea Lab.

[Stability of symbionts in corals] - Diversity, distribution, and temporal stability of coral 'zooxanthellae' on a Pacific reef evaluated with samples collected in Palau from 2013 to 2022 (Collaborative Research: Stability, flexibility, and functionality of thermally tolerant coral symbioses)

This data set provides information about the long-term composition of symbiont populations within individual coral colonies. Diverse coral taxa (Scleractinia) from a West Indo-Pacific fore reef (Palau) were tagged and sampled at various intervals--ranging from six months to several years--over nine years' time. Symbiont identity was examined using multiple genetic markers that resolved symbiont diversity to species and individual genotypes (i.e. clonal strains). Consistent with previous colony monitoring studies, symbiont populations in a majority of colonies were dominated by one species and one strain (based on multi-locus genotyping) over multiple years. Thus, the distribution of symbiont diversity at the genus, species and clone level, comprising specific and stable partner combinations, scale predictably to reef habitat, host taxon, and individual colony.

[STING 1 TDN and TDP concentration] - Total dissolved nitrogen (TDN) and total dissolved phosphorus (TDP) of samples collected on the West Florida Shelf during STING I cruise AE2305 on R/V Atlantic Explorer from Feb 20 to Mar 05, 2023 (Collaborative Research: Linking iron and nitrogen sources in an oligotrophic coastal margin: Nitrogen fixation and the role of boundary fluxes)

The West Florida Shelf (WFS) is oligotrophic, with inorganic N and P concentrations typically at or below detection limits, and yet significant rates of primary productivity, including blooms of the cyanobacterial diazotroph Trichodesmium spp. as well as the harmful algal species Karenia brevis, are observed there. Consequently, dissolved organic nitrogen (DON) and dissolved organic phosphorus (DOP) are thought to be the primary sources of assimilative nutrients on the WFS. Here we report measurements of total dissolved nitrogen (TDN) and total dissolved phosphorus (TDP) concentrations made on samples collected on a cross-shelf cruise in Feb-Mar 2023 aboard the R/V Atlantic Explorer. Elevated concentrations of TDN (>12 µM) and TDP (>0.5 µM) were observed in the shallow, nearshore region, while to the west concentrations of both TDN and TDP decreased to values typically associated with oligotrophic North Atlantic waters (4 to 5 µM TDN and 0.05 to 0.1 µM TDP).

[STING macronutrient concentrations] - Dissolved Macronutrient Concentrations from Depth Profiles and Incubation Experiments from STING I Cruise AE2305 on R/V Atlantic Explorer in the Gulf of Mexico from February to March 2023 (Collaborative Research: Linking iron and nitrogen sources in an oligotrophic coastal margin: Nitrogen fixation and the role of boundary fluxes)

Concentrations of inorganic dissolved macronutrients, including phosphate, nitrate plus nitrite (N+N), silicic acid, and nitrite, from phytoplankton shipboard incubation experiments and depth profiles collected on STING I cruise AE2305 on R/V Atlantic Explorer in the Gulf of Mexico from February to March 2023.

This project investigates how groundwater discharge delivers important nutrients to the coastal ecosystems of the West Florida Shelf. Preliminary studies indicate that groundwater may supply both dissolved organic nitrogen (DON) and iron in this region. In coastal ecosystems like the West Florida Shelf that have very low nitrate and ammonium concentrations, DON is the main form of nitrogen available to organisms. Nitrogen cycling is strongly affected by iron availability because iron is essential for both photosynthesis and for nitrogen fixation. This study will investigate the sources and composition of DON and iron, and their influence on the coastal ecosystem. The team will sample offshore groundwater wells, river and estuarine waters, and conduct two expeditions across the West Florida Shelf in winter and summer.

[Submarine groundwater discharge on conspecific interactions] - Coral physiologic response data from study of conspecific interactions between corals mediate the effect of submarine groundwater discharge on coral physiology in Mo'orea, French Polynesia in 2021 (RUI: Collaborative Research: Defining the biogeochemical context and ecological impacts of submarine groundwater discharge on coral reefs)

This dataset reports physiological metrics of corals, including chlorophyll content, endosymbiont density, photosynthesis, and respiration rates, collected during experiments examining the effects of conspecific interactions and submarine groundwater discharge on coral health.

Study description:

Land-based inputs, such as runoff, rivers, and submarine groundwater, can alter biological processes on coral reefs. While the abiotic factors associated with land-based inputs have strong effects on corals, corals are also affected by biotic interactions, including other neighboring corals. The biological responses of corals to changing environmental conditions and their neighbors are likely interactive; however, few studies address both biotic and abiotic interactions in concert. In a manipulative field experiment, we tested how the natural environmental gradient created by submarine groundwater discharge (SGD) affected holobiont and symbiont metabolic rates and endosymbiont physiology of Porites rus. We further tested how the effect of SGD on the coral was mediated by intra and interspecific interactions. SGD is a natural land-sea connection that delivers nutrients, inorganic carbon, and other solutes to coastal ecosystems worldwide. Our resus show that a natural gradient of nutrient enrichment and pH variability as a result of acute SGD exposure generally benefited P. rus, increasing gross photosynthesis, respiration, endosymbiont densities, and chlorophyll a content. Conspecifics in direct contact with the a neighboring coral, however, altered the relationship between coral physiology and SGD, lowering the photosynthetic and respiration rates from expected values when the coral had no neighbor. We show that the response of corals to environmental change is dependent on the types of nearby neighbor corals and how neighbors alter the chemical or physical environment around the coral. Our study underscores the importance of considering biotic interactions when predicting the physiologic responses of corals to the environment.

[Substrate Coverage] - Percent coverage along a transect or subsample of each of four substrate types recorded during emergent and rapid emergent surveys conducted in the subtidal zone of northern California, Sonoma and Mendocino counties, from 1999 to 2023 (Collaborative Research: The effects of marine heatwaves on reproduction, larval transport and recruitment in sea urchin metapopulations)

The Kelp Forest Monitoring data record span surveys across 24 years from 1999 through 2023 at 20 locations on the Sonoma-Mendocino Coast, Northern California, and span the major marine heatwave of 2014-2016. Years without data, inclusive: 2002, 2020, 2021. These surveys are ongoing and are conducted by the California Department of Fish and Wildlife dive team with participation from dive program partners at UC Davis, UC Santa Cruz, Cal Poly Humboldt, Sonoma State and other dive programs and volunteers. Not all sites were surveyed in all years. Surveys prior to 2003 were not conducted by the same teams or with the same methods except that all surveys were done using Scuba along 30 x 2m transects randomly placed in the subtidal zone in rocky habitats dominated by bull kelp, Nereocystis luetkeana, forests. These randomly placed band transects surveys were stratified by depth (A=0-15, B=16-30, C=31-45, D=46-60 ft) as we know sea urchin and abalone populations differ by depth.

Data collected include the number of live, dying (in some years during the mass mortality events), and sea urchins (red-Mesocentrotus franciscanus and purple-Strongylocentrotus purpuratus), red abalone (Haliotis rufescens), pinto abalone (H. kamtschatkana), flat abalone (H. walallensis), as well as empty abalone shells (again in some years). Additional data collected (if scuba bottom time and/or air allowed): red abalone size, numbers or presence of associated species such as sea stars and predators, algal group quantification, and presence of bull kelp, substrate type. Data on algae and associated species differed depending on the year and the focus of the studies in response to ecosystem conditions but all years quantified sea urchins and abalones.

This dataset provides in situ estimates of the coverage of the substrate along each survey transect as a percentage of four substrate types: reef, boulder, cobble, and sand.

[Subterranean Estuary In Situ Tracer Experiment Incubation Data, 2019] - In situ tracer injection experiment conducted with 15N-labeled ammonium in a shallow, sandy subterranean estuary in Gloucester Point, USA  in August 2019. (Collaborative Research:  Cryptic nitrogen cycling in the anoxic subterranean estuary)

These data are the result of an in situ tracer injection experiment conducted with 15N-labeled ammonium to determine the fate and transport rates of ammonium within a shallow, sandy subterranean estuary in Gloucester Point, VA, USA.

Replicate injections of 15N-labeled ammonium, sulfur hexaflouride, and bromide amended porewater were injected into piezometers at 50cm.  Porewater was then collected overtime from the injection piezometers and tracer piezometers surrounding the injection site ranging in depth from 40-60cm.  At each time point, samples were collected to analyze dissolved inorganic nitrogen (nitrate, nitrite, and ammonium) concentrations, sulfur hexaflouride, bromide, chloride. Nitrate and nitrite samples from porewater were analyzed with an isotope ratio mass spectrometer in order to assess the 15N enrichment of the nitrate in each sample resulting in a delta value (d15N) that allows for the calculation of the mole fraction of 15N-labeled nitrite and nitrate in porewater at each time point. The production or consumption over time constitutes subterranean estuary nitrogen cycling rates (e.g. nitrification, denitrification, etc.).

These data are the result of a sediment slurry incubation experiment conducted with 15N-labeled ammonium to quantify nitrification rates in the sediments of a shallow, sandy subterranean estuary in Gloucester Point, VA, USA. Triplicate sediment cores that were 50cm in length were collected and sectioned into 10cm intervals. Homogenized sediment was incubated with porewater from the same depth interval that had been amended with 15N-labeled ammonium. Sediments were incubated in the dark for zero, six and twelve hours. At each time point, samples were collected to analyze dissolved inorganic nitrogen (nitrate, nitrite, and ammonium) concentrations. Samples were analyzed with an isotope ratio mass spectrometer in order to assess the 15N enrichment of the nitrate in each sample resulting in a delta value (d15N) that allows for the calculation of the mole fraction of 15N-labeled nitrate produced by each slurry. This production over time constitutes the sediment nitrification rate for each depth interval.

Ocean water temperatures were collected from May 14, 1992 to August 22, 2023 (these logger deployments are ongoing) from 10 meters benthic depth, at Van Damme State Park, Mendocino County, Northern California. Water temperatures were collected with Onset Hobotemp® and TidbiT® temperature loggers in degrees Celsius. Data are presented as daily averages of 10-minute minimum intervals.

Ocean water temperatures were collected to document long-term temperature conditions on the bottom at the level of the reef. Loggers were placed 1 meter off the bottom on stainless steel cages used to monitor juvenile abalone and sea urchin recruitment at this reference location.

Water temperatures are presented as daily averages for the period of record. Some data gaps exist due to equipment failure, loss, or rough conditions precluding placement of data loggers. The data gaps are listed in the “Problems/Issues” section below.

These data are unique in that they are benthic seawater temperature data (1 meter from the bottom where the benthic animals live) which can be used to compare with the more readily available sea surface temperature data.

[Sulfate triple oxygen isotope signatures in Messinian evaporite and barite] - Sulfate triple oxygen isotope signatures in Messinian evaporite and barite from cores collected (Collaborative Research: Development of a novel way for understanding ancient Earth atmospheres and marine sulfate using the stable isotope of Oxygen (17O) in marine barite.)

These data include the triple oxygen isotope compositions (Delta'17O and delta18O) of marine sulfate minerals, including Messinian-age evaporite, Messinian-age barite, and modern barite. Samples were collected from outcrop (Messinian evaporite from the Caltanissetta and Sorbas Basins) as well as from Integrated Ocean Drilling Program (IODP) cores (evaporite from the Tyrrhenian Basin, and all barite). Instruments used to measure the oxygen isotope compositions included a High Temperature Conversion Elemental Analyzer (TC/EA) coupled to a Delta V Plus Isotope Ratio Mass Spectrometer (IRMS) and a custom built laser fluorination line coupled to a 253 Plus IRMS, in the Johnston lab at Harvard University. These measurements contributed to our understanding of how closely marine evaporite sulfate records reflect ancient seawater sulfate isotope composition and the degree to which sulfate within an evaporite basin is microbially cycled. Anna Waldeck and Haley Olson, both students in David Johnston's lab, measured the oxygen isotope compositions.

[Summary data from the Heatwaves and Coral-Recovery Database (HeatCRD)] - Summary data from the Heatwaves and Coral-Recovery Database (HeatCRD) covering global coral reef sites from 1977-2020 (Thermal stress and differential recovery of coral reefs)

This dataset is a summary table of the Heatwaves and Coral-Recovery Database (HeatCRD) introduced in van Woesik and Kratochwill (2024). The HeatCRD is the most comprehensive reference on coral recovery following marine heatwaves and other disturbances, encompassing 29,205 data records spanning 44 years from 12,266 sites, 83 countries, and 160 data sources. These data provide essential information to coral-reef scientists and managers to best guide coral-reef conservation efforts at both local and regional scales.
The dataset includes metadata for coral reef sampling events, such as site descriptions, geographical coordinates, depth, distance to shore, exposure, turbidity, coral cover percentages, MPA descriptions, temperature measurements, windspeed, and thermal stress indicators over 23 years.

[Surface Sedimentary Black Carbon Concentrations and Carbon Isotopes Values] - Surface Sedimentary Black Carbon Concentrations, Flux, and Carbon Isotopes Values from the R.V. Endeavor EN651 in the Equatorial Atlantic Ocean from March 2020 (Concentrations and source assessment of black carbon across tropical Atlantic air and sediment)

Surface sediments (0-1 cm) were obtained from the equatorial Atlantic Ocean and isolated for black carbon using the chemothermal oxidation at 375°C method (CTO 375). Multicores were taken aboard the R.V. Endeavor (EN651) from March 1st through March 15th, 2020, using a multi corer MC-800. Sediment samples were collected from 12 multicore stations along a west-to-east transect of the equatorial Atlantic centered on about 5˚N. Sediment deposition environments included the Amazon Submarine Fan, a series of sites across the Mid-Atlantic Ridge, and sites on the Sierra Leone Rise and adjacent Sierra Leone Basin. See Figure 1 in the EN651 cruise report (Lohmann 2020) for an illustration of coring site locations.

Background information taken from the EN651 cruise report (Lohmann 2020)

Black carbon (BC) is a highly graphitized incomplete combustion byproduct that could be a sink for fixed carbon, especially when deposited to pelagic sediments (Kuhlbusch 1998). There is a general assumption that rivers deliver most or all BC to the ocean (Coppola et al. 2018; Elmquist et al. 2008; Kuhlbusch 1998; Masiello and Druffel 2001; Mitra et al. 2014, 2002; Suman et al. 1997). Yet the effects and fluxes of BC are not well constrained in general circulation models. For example, few BC flux measurements are available in remote ocean sediments due to the expense and difficulty of obtaining samples. The formation of BC during incomplete combustion results in a fraction of carbon not being available for the biological pump and deep ocean respiration. Once deposited to the ocean, BC is buried in sediments and can account for significant fractions of the organic matter preserved in sediments. Hence, our results would contribute towards accounting for some of the ‘missing' terrestrial OC in sediments, as all BC is landmass derived (Hedges et al. 1997).
