[Little Cayman Vertical Temp Data] -  (NSF-BSF: Assessing the mechanisms of molecular and morphological adaptation by corals to extreme environments)

Summary:
Coral reefs are increasingly threatened by marine heatwaves, which drive widespread coral bleaching and mortality. Mesophotic coral ecosystems (MCEs) have been proposed as potential thermal refuges due to their greater depth and relative isolation from surface temperature extremes. Yet their resilience to extreme heat events remains uncertain, with location specific conclusions, thus requiring further studies. Here, we investigate the effects of the 2023 marine heatwave in the Cayman Islands, which resulted in prolonged sea surface temperatures exceeding 31°C and 17.5 DHW with extensive bleaching across shallow coral reefs.

Utilizing vertical transect surveys from 10m to 50m, we assessed depth-related variations in bleaching prevalence and temperature profiles. Our results indicate a significant decline in bleaching with increasing depth, with a concurrent reduction in temperature. Depth-generalist species exhibited reduced bleaching at greater depths, whereas shallow-water specialists displayed severe bleaching. These findings suggest that while MCEs may provide thermal refuge for some species, their capacity to buffer against climate-driven reef degradation is species-specific. Given the increasing frequency and intensity of marine heatwaves, understanding the role of deeper reef habitats in mitigating coral loss is critical for informing conservation and management strategies.

Our study underscores the importance of protecting MCEs as potential thermal refuges while emphasizing the need for continued research on species-specific thermal resilience with depth. Within this dataset, we present the temperature data measured during each survey across depth.

[Lobster Larvae Growth and Mortality Data] - Growth and mortality of lobster larvae at different temperatures for lobster larvae from Gulf of Maine near Boothbay Maine from 2021 and 2022 (Lobster Thermal Thresholds project) (RUI: Collaborative Research: Linking physiological thermal thresholds to the distribution of lobster settlers and juveniles)

Summary:
We used the American lobster (Homarus americanus lsid:marinespecies.org:taxname:156134) in the Gulf of Maine as a model system to define thermal tolerance in larvae and establish mechanistic linkages between thermal tolerance of the individual larva and the patterns of settlement in the field.  We assessed and compared the thermal tolerances of larvae reared in the laboratory using conventional methods with larvae captured in the wild, and examined ontogenetic changes in thermal tolerance.  The upper and lower thermal thresholds larval stages I-IV and the first juvenile stage were defined in part by growth and mortality when subjected to chronic exposure to different treatment temperatures until they either molted to the next developmental stage or died.  This data set includes individuals dying, the size after molting and the amount of time elapsed between the start of the treatment and either molting or death.

[Log_Kd] - Partition coefficient of 234Th, 233Pa, 210Pb, 210Po, and 7Be (Biopolymers as carrier phases for selected natural radionuclides (of Th, Pa, Pb, Po, Be) in diatoms and coccolithophores)

Summary:
Laboratory studies were conducted to examine the sorption of selected radionuclides (234Th, 233Pa, 210Po, 210Pb, and 7Be) onto inorganic (pure silica and acid-cleaned diatom frustules) and organic (diatom cells with or without silica frustules) particles in natural seawater and the role of templating biomolecules and exopolymeric substances (EPS) extracted from the same species of diatom, Phaeodactylum tricornutum, in the sorption process. The range of partition coefficients (Kd, reported as logKd) of radionuclides between water and the different particle types was 4.78\u20136.69 for 234Th, 5.23\u20136.71 for 233Pa, 4.44\u20135.86 for 210Pb, 4.47\u20134.92 for 210Po, and 4.93\u20137.23 for 7Be, similar to values reported for lab and field determinations. The sorption of all radionuclides was significantly enhanced in the presence of organic matter associated with particles, resulting in Kd one to two orders of magnitude higher than for inorganic particles only, with highest values for 7Be (logKd of 7.2). Results further indicate that EPS and frustule-embedded biomolecules in diatom cells are responsible for the sorption enhancement rather than the silica shell itself. By separating radiolabeled EPS via isoelectric focusing, we found that isoelectric points are radionuclide specific, suggesting that each radionuclide binds to specific biopolymeric functional groups, with the most efficient binding sites likely occurring in acid polysaccharides, iron hydroxides, and proteins. Further progress in evaluating the effects of diatom frustule\u2013related biopolymers on binding, scavenging, and fractionation of radionuclides would require the application of molecular-level characterization techniques.

[Longitudinal study NCBI SRA] - NCBI Sequence Read Archive (SRA) accession numbers for fastq sequence files of 16S amplicons from a longitudinal study of SCTLD at St. John, U.S. Virgin Islands from 2020 to 2024 (A multi-scale approach to predicting infectious multi-host disease spread in marine benthic communities)

Summary:
In St. John, U.S. Virgin Islands, a longitudinal study of Colpophyllia natans was conducted. Six corals per site (two sites) were tagged and repeatedly sampled from July 2020 through March 2024, during which time, stony coral tissue loss disease (SCTLD) arrived on the reefs. As the tagged corals contracted SCTLD, coral tissue and near-coral seawater (2-5 centimeters from colony surface) were collected. Coral tissue was separated from the coral skeleton, and the seawater was filtered through 0.2-micrometer (µm) filters. DNA was extracted from the tissue and filters, and 16S ribosomal RNA gene sequencing was done to determine the bacteria and archaea communities that live within and near the corals. The goal of the study was to determine how coral-associated microbiomes are affected by the arrival of SCTLD through time. This data set contains the fastq files of the 16S amplicon sequencing of the coral tissue and near-coral seawater communities.

[Macroalgal biodiversity experiment: coral growth and tissue mortality data] - Coral (Pocillopora verrucosa) growth and tissue mortality from experimental field plots in Moʻorea, French Polynesia in 2021 (Positive Effects of Coral Biodiversity on Coral Performance: Patterns, Processes, and Dynamics)

Summary:
Hundreds of studies now document positive relationships between biodiversity and critical ecosystem processes, but as ecological communities worldwide shift towards new species configurations, less is known regarding how biodiversity of undesirable species will shape the functioning of ecosystems or foundation species. We manipulated macroalgal species richness in experimental field plots to test whether and how identity and diversity of competing macroalgae affected the growth, survival, and microbiome of a common coral in Moʻorea, French Polynesia. These data include coral (Pocillopora verrucosa) percent growth and tissue mortality among corals outplanted into 25 cm x 21 cm experimental plots in the back reef lagoon on the north coast of Moʻorea, French Polynesia (17°28′37″S 149°50′21″W). We varied the macroalgal community on the upper surface of each plot by outplanting monocultures holding similar masses of: (1) Sargassum pacificum, (2) Turbinaria ornata, or (3) Amansia rhodantha, as well as (4) polycultures containing all three species (12 plots per treatment; Figure 1 of Clements et al., 2024). There were also two additional treatments: (5) plots with plastic algal mimics to control for effects of shading or abrasion unrelated to the biotic properties of live seaweeds and 6) control plots where corals, but not living algae or physical mimics, were present (n = 12 plots/treatment).

This dataset includes coral (Pocillopora verrucosa) growth and tissue mortality at 9 weeks for plots with no algae (control), plastic algal mimics, monocultures of Amansia rhodantha, Turbinaria ornata, or Sargassum pacificum, and polycultures containing all three algal species.

Summary:
An experiment examining the effects of water residence time upon Saccharina latissima capacity to ameliorate seawater acidity under ambient and simulated future scenarios of climate change in a gradient of irradiance was conducted indoors using tanks with a flow-through seawater system based at the Bigelow facilities in November 2018. In a previous experiment (experiment 1), we explored the individual capacities of four species of marine macrophytes (Ulva lactuca, Zostera marina, Fucus vesiculosus and Saccharina latissima) to ameliorate seawater acidity in experimentally elevated pCO2. Then in this experiment 2, we used the most responsive species (i.e., Saccharina latissima) to assess the effects of high and low water residence time on the amelioration of seawater acidity in ambient and simulated future scenarios of climate change across a gradient of irradiance.

This dataset includes data from experiment 2, residence time and irradiance, described in the manuscript: Optimizing marine macrophyte capacity to locally ameliorate ocean acidification under variable light and flow regimes: Insights from an experimental approach (Ricart, A. M. et al. 2023).

Summary:
This dataset includes the concentrations of seven major inorganic ions determined in primary marine aerosol (PMA) samples collected from the Bermuda Atlantic Time-series Study (BATS) station during a summer cruise in 2021 and a winter cruise in 2023 aboard the R/V Atlantic Explorer. The major ions in PMA samples were collected using a high-capacity aerosol generator and the major ions were quantified using a Dionex dual channel model ICS 6000 high-performance ion chromatograph (ICS-6000 DP). This dataset was generated and prepared by Dr. Lei Xue under the supervision of Dr. David Kieber at the State University of New York, College of Environmental Science and Forestry. These data were used to determine the enrichment of major ions in PMA samples and to calculate the enrichment factors of protein/peptides and carbohydrates in PMA samples relative to bulk seawater and the associated seasonal variability. This work is part of a larger study to understand the seasonal variability in the fraction of refractory organic carbon in primary marine aerosol at the BATS station.

[Manually annotated reef halos from 6 study areas] - Manually annotated reef halos based on sattelite imagery from 6 study areas as training and test data for a deep learning model (CAREER: Decoding seascape-scale vegetation patterns on coral reefs to understand ecosystem health: Integrating research and education from organismal to planetary scales)

Summary:
Reef halos are rings of bare sand that surround coral reef patches. Halo formation is likely to be the indirectly result of interactions between relatively healthy predator and herbivore populations. To reduce the risk of predation, herbivores preferentially graze close to the safety of the reef, potentially affecting the presence and size of the halo. Reef halos are readily visible in remotely sensed imagery, and monitoring their presence and changes in size may therefore offer clues as to how predator and herbivore populations are faring. However, manually identifying and measuring halos is slow and limits the spatial and temporal scope of studies. There are currently no existing tools to automatically identify single reef halos and measure their size to speed up their identification and improve our ability to quantify their variability over space and time.

Here we present a set of convolutional neural networks aimed at identifying and measuring reef halos from very high-resolution satellite imagery (i.e., ∼0.6 m spatial resolution). We show that deep learning algorithms can successfully detect and measure reef halos with a high degree of accuracy (F1 = 0.824), thereby enabling faster, more accurate spatio-temporal monitoring of halo size. This tool will aid in the global study of reef halos, and potentially coral reef ecosystem monitoring, by facilitating our discovery of the ecological dynamics underlying reef halo presence and variability.

Summary:
This project addresses carbon conversion processes in sandy beaches. To assess gas concentration gradients between the atmsphere and the beach sediment, vertical gas concentration profiles were measured below the beach sediment surface. Gas (custom probes) and temperature probes (PT100) were placed at 2.5 cm above the sediment and at -5, -15 and -25 cm below the sediment surface. Pore gas was extracted from the sediment using a syringe pump (150 ml max. volume). Gas concentrations were measured with a Licor850. The instrument recorded CO2 concentration, (ppm) and H2O concentration, (ppt).

The experiment investigated impacts of contemporary high pCO2 and imposed dynamic historical temperature trends on multiple aspects of individual thermal performance. Morphometrics included test diameter and height, overall wet mass, gonad wet mass, overall dry mass, gonad dry mass, overall ash mass, and gonad ash mass. Test dimensions were measured using digital calipers (Mitutoyo America Corporation®, Aurora IL, USA). Mass measurements were made using a calibrated digital scale (Mettler-Toledo, LLC., Columbus, OH, USA). Ocean warming and acidification threaten the stability of foundation species not just through direct physiological stress, but also indirectly via impacts on primary consumption. However, the effects of these drivers on this critical ecological interaction may not be generalizable due to complex energetic impacts on both consumers and their resource(s). Therefore, understanding consumer responses to multiple drivers and dynamic conditions are especially important for key taxa, such as S. purpuratus, which exert strong grazing impacts on kelp forests. All animals were simultaneously collected from Ucluelet, British Columbia, Canada (48° 56.604N, 125° 34.699W) from a depth of 7-8 m relative to mean low tide on 3 September 2021 using SCUBA and immediately transported to the Marna Laboratory flow through seawater system. Animals were haphazardly selected and assigned to the "Wild" group or "Experimental" group (and thereafter treatments) from this pool.

[Marsh channel monitoring data] - Continuously monitored water quality parameters from three open-water sites in a tidal salt marsh channel in New Jersey, USA from June 2021 to June 2024 (Sediment transport and water quality in watersheds and coastlines of the United States)

Summary:
This dataset includes high-frequency measurements of key physical and biogeochemical parameters (depth, salinity, temperature, dissolved oxygen concentration and % saturation, pH, turbidity, chlorophyll a) collected at 10-minute intervals from three open-water platforms in a salt marsh tidal channel. The marsh is located landward of Seven Mile Island, a populated barrier island in Cape May County, New Jersey, and is a part of the Seven Mile Island Innovation Laboratory (SMIIL), a research initiative focused on advancing dredging and marsh restoration practices. Data were collected using In-Situ Aqua TROLL 600 multiparameter sondes, which were cleaned, recalibrated, and swapped every 4–12 weeks to enable continuous monitoring. Turbidity and chlorophyll a data are included but have highly variable coverage. The dataset comprises 18 deployments, which have been appended and quality controlled. Meteorological data (air temperature, relative humidity, atmospheric pressure) from a centrally located Young ResponseONE Weather Transmitter and Onset HOBO water level logger, along with ERA5 wind speed data, are provided for the same time period. This high-resolution, multi-year dataset supports the analysis of aquatic ecosystem metabolism and environmental variability in a marsh-dominated estuary, a system type that remains underrepresented in long-term, high-frequency monitoring efforts.

[Mask R-CNN and U-Net models and reef halo ouput calculations] - Mask R-CNN and U-Net model and output of coral reef halo measurements based on global multispectral satellite imagery (CAREER: Decoding seascape-scale vegetation patterns on coral reefs to understand ecosystem health: Integrating research and education from organismal to planetary scales)

Summary:
Reef halos are rings of bare sand that surround coral reef patches. Halo formation is likely to be the indirectly result of interactions between relatively healthy predator and herbivore populations. To reduce the risk of predation, herbivores preferentially graze close to the safety of the reef, potentially affecting the presence and size of the halo. Reef halos are readily visible in remotely sensed imagery, and monitoring their presence and changes in size may therefore offer clues as to how predator and herbivore populations are faring. However, manually identifying and measuring halos is slow and limits the spatial and temporal scope of studies. There are currently no existing tools to automatically identify single reef halos and measure their size to speed up their identification and improve our ability to quantify their variability over space and time.

Here we present a set of convolutional neural networks aimed at identifying and measuring reef halos from very high-resolution satellite imagery (i.e., ∼0.6 m spatial resolution). We show that deep learning algorithms can successfully detect and measure reef halos with a high degree of accuracy (F1 = 0.824), thereby enabling faster, more accurate spatio-temporal monitoring of halo size. This tool will aid in the global study of reef halos, and potentially coral reef ecosystem monitoring, by facilitating our discovery of the ecological dynamics underlying reef halo presence and variability.

[McMurdo Sound acoustic backscatter krill and silverfish] - Acoustic backscatter from krill and silverfish in McMurdo Sound from 2014-2015 (Food web dynamics in an intact ecosystem: the role of top predators in McMurdo Sound)

Summary:
Krill and fish were sampled acoustically and visually beneath the fast ice
using the tethered SCINI ROV, which was deployed and operated through a 25 cm
diameter hole drilled through the sea ice. SCINI contained cameras and
thrusters, and towed a sensor package consisting of a WET Labs fluorometer
(ECO-AFL/FL) and a single-beam Biosonics 120 kHz DT-X echosounder. Visual
targets were identified to the lowest taxon possible; these observations were
used primarily to verify classification of acoustic signals. The echosounder
operated at a nominal ping rate of 1 ping s-1; however, this rate was
occasionally adjusted if false bottom signals were observed. The general
profile of a dive included a surface transect of ~300 m horizontal distance,
where the acoustic transducer faced downward, and also a dive to ~120 m if
conditions allowed. Echogram data were saved to a depth of 500 m, and
background noise was removed. Given the effective range of the transducer of
approximately 100 m (resolving -80 dB targets), surveys characterized the
upper 200 m of the water column.

[Measurements of treatment tub seawater conditions: pH and total alkalinity] - pH and total alkalinity measurements of treatment tub seawater during lab experiments conducted in spring 2022. (Influence of environmental pH variability and thermal sensitivity on the resilience of reef-building corals to acidification stress)

Summary:
Ocean acidification (OA) resulting from anthropogenic CO2 emissions is impairing the reproduction of marine organisms. While parental exposure to OA can protect offspring via carryover effects, this phenomenon is poorly understood in many marine invertebrate taxa. We examined how parental exposure to acidified (pH 7.40) versus ambient (pH 7.72) seawater influenced reproduction and offspring performance across six gametogenic cycles (13 weeks) in the estuarine sea anemone Nematostella vectensis. This dataset contains data resulting from measurements of treatment tub seawater conditions, including pH and total alkalinity.

[Megafauna counts by taxon in image surveys at inactive sulfides on the East Pacific Rise] - Megafauna counts by taxon in images collected during three surveys (December 25, 2019, April 7 and 9, 2021) with deep-submergence vehicles at inactive sulfide mounds on the East Pacific Rise. (Collaborative Research: Life after Death: Do Inactive Sulfides Fuel a Unique Ecosystem at the Deep Seafloor?)

Summary:
This dataset includes counts by taxon for megafauna in images collected during surveys with deep-submergence vehicles at inactive sulfide mounds near the 9 50' N hydrothermal vent field on the East Pacific Rise. Images were collected with a down-looking digital still camera. We provide image areas for estimating megafauna density (counts per area of seafloor). Here we provide data from three surveys: one during HOV Alvin Dive 5044 at Lucky's Mound on 25 December 2019 on cruise AT42-21 and two during ROV Jason II Dives 1309 and 1311, on the oceanic rise (between Lucky's Mound and Sentry Spire) on 7 April 2021 and at Sentry Spire on 9 April 2021, respectively, on cruise RR2102. Megafauna were manually annotated to morphotype using ImageJ software. Morphotypes were identified to the lowest taxonomic level and assigned to a feeding mode. This dataset is provided in two formats: long-format comma-separated variable (csv) file and wide-format Excel (xlsx) file. This dataset is analyzed in a manuscript by Meneses et al. (2024).

[Mesocosm CB 2021 Light and Temperature] - Light and temperature data for mesocosm incubation experiment simulating a phytoplankton bloom in Chesapeake Bay August 2021 (Marine Diatom-Parasite Relationships in Upwelling Systems)

Summary:
A mesocosm experiment was performed in August 2021 on the R/V Hugh Sharp, cruise HRS2110, at a station near the mouth of Chesapeake Bay to simulate a phytoplankton bloom and to assess changes in assemblage and biogeochemical processes while excluding changes due to advection. Three 20-L carboys were filled with filtered bay water, inoculated with surface water and sampled daily for a week. Nutrient concentrations, nitrate and bicarbonate uptake rates, pigment concentrations and samples for 18S rRNA gene sequence analysis were collected once or more times per day. 15NO3- and H13CO3- tracer incubations were performed alongside pigment and DNA sampling to compare temporal trends in community composition and primary productivity (nitrogen (N) and carbon (C) transport rates). These results address the nature of phytoplankton blooms, and present a more complex relationship between bloom progression and phytoplankton diversity that usually assumed or detected by traditional methods. This dataset contains the light and temperature data logged for the three replicate mesocosms over the course of the simulated bloom. These data were collected by Jenna Lee from Princeton University.

[mesozooplankton biomass] - Mesozooplankton biomass from MOCNESS tows collected during R/V Oceanus cruises OC415-01, OC415-03, OC404-01, OC404-04 in the Sargasso Sea, 2004-2005 (EDDIES project) (Eddies Dynamics, Mixing, Export, and Species composition)

Summary:
Zooplankton biomass estimates were determined from 1 m^2, 150 micron mesh
MOCNESS (Multiple Opening/Closing Net and Environmental Sensing System) tows.
The following discrete depth intervals were sampled on the upcast: 0-50,
50-100, 100-150, 150-200, 200-300, 300-400, 400-500, 500-600, and 600-700 m.
Generally paired tows during the day (9:30-15:00 local time) and night
(21:30-03:00) were performed at each station. A single tow generaly covered
5-15 km.\u00a0 The nominal position (lat_n and lon_n) for each tow is the
position at the mid depth 200-300m sampling interval.\u00a0 Table 1 ([pg 1362

NOTES/Goldthwait_Steinberg_2008_Table1.pdf\\)) of Goldthwait and Steinberg
(2008) is a sequential list of all MOCNESS mesozooplankton tows and includes
eddy identification number and location.

Each sample was size-fractionated using nested sieves of 0.15 mm, 0.5 mm, 1
mm, 2mm, and 5 mm mesh. Zooplankton in each size class were transferred onto
pre-weighed 0.15 mm nitex mesh filters and rinsed with deionized water.
Samples were then dried for 24 hours at 60 degrees C and weighed.
