This datafile contains frequencies and sizes (number of polyps killed) developed in coral tissues after the application and removal of fish feces to test whether fish from different guilds affect coral health in distinct ways.There were five treatments: fresh feces from a corallivorous butterflyfish (FC); fresh feces from a grazer/detritivore (FG); sterilized feces from a corallivorous butterflyfish (SC); sterilized feces from a grazer/detritivore (SG); no-feces control (C). For the fresh feces treatments (FC, FG), we applied 100 µl of fresh feces isolated from the hindgut of the butterflyfish Chaetodon ornatissimus (FC) or the grazer/detritivore Ctenochaetus striatus (FG) directly onto each coral fragment. For the sterilized feces treatments (SC, SG), fecal pellets were sterilized in a pressure cooker for 40 minutes at 120°C and then applied in the same manner as fresh feces. The experiment ran for ~22 hours. The experiment was conducted in three iterations in Mo'orea, French Polynesia, over two years (2020, 2021).

[Coral reef benthic composition in SGD] - Impacts of submarine groundwater discharge on benthic community composition and functional diversity on coral reefs in Mo'orea, French Polynesia from Aug 2021 to Jun 2022 (RUI: Collaborative Research: Defining the biogeochemical context and ecological impacts of submarine groundwater discharge on coral reefs)

Coral reefs experience numerous natural and anthropogenic environmental gradients that alter biophysical conditions and affect biodiversity. While many studies have focused on drivers of reef biodiversity using traditional diversity metrics (e.g., species richness, diversity, evenness), less is known about how environmental variability may influence functional diversity. In this study, we tested the impact of submarine groundwater discharge (SGD) on taxonomic and functional diversity metrics in Mo'orea, French Polynesia. SGD is the expulsion of terrestrial fresh or recirculated seawater into marine environments and is associated with reduced temperatures, pH, and salinity and elevated nutrient levels. Using a regression approach along the SGD gradient, we found that taxon and functional-entity richness displayed unimodal relationships to SGD parameters, primarily nitrate + nitrite and phosphate variability, with peak richness at moderate SGD for stony coral and the full benthic community. Macroalgae showed this unimodal pattern for functional-entity but not taxonomic richness. Functional community composition (presence and abundance of functional entities) increased along the gradient, while taxonomic composition showed a nonlinear relationship to SGD-related parameters. SGD is a common feature of many coastal ecosystems globally and therefore may be more important to structuring benthic functional diversity than previously thought. Further, studying community shifts through a functional-trait lens may provide important insights into the roles of community functions on ecosystem processes and stability, leading to improved management strategies. This dataset includes site identifiers and survey metadata, substrate composition, structural complexity (rugosity), seawater parameters (salinity, temperature, pH, nutrients), taxonomic and functional traits of benthic taxa (morphology, calcification strategy, trophic group), proportional cover of benthic taxa, and community-level diversity metrics.

[Coral trait variation] - Growth and chlorophyll density of individual fragments of the coral Porites divaricata measured during a reciprocal transplant experiment conducted at three sites in Turneffe Atoll, Belize from February to July 2022 (OCE-PRF: Drivers of phenotypic diversity and adaptation in asexually propagating coral populations)

We sought to investigate the role of genetic, intra-clonal, and environmental variation in driving variation in fitness-related traits in the Caribbean thin finger coral, Porites divaricata (Taxonomy ID: 262287). We conducted a reciprocal transplant experiment whereby fragments from individual coral colonies of known genetic background were transplanted to three sites from February to July 2022. These sites included two mangrove sites and one reef site at Calabash Caye, Turneffe Atoll, Belize. Prior to and post-transplanting, fragments were measured to determine growth rate over this time. Coral fragments were also photographed to determine red channel intensity, which serves as a proxy for chlorophyll density.

This dataset contains the measures of these two coral traits (coral fragment growth and chlorophyll density (red channel intensity)) for each coral individual and also contains metadata about the genotype, origin site, transplanted site, rope at transplanted site, and age.

A related dataset contains environmental information about each transplanted site over this time period, based on loggers that recorded temperature and light levels. Data were collected by scientists at the University of Texas at Austin and the University of Belize.

[Coral transplant site environmental data] - Temperature and light intensity measured at each transplant site during a reciprocal transplant experiment conducted at three sites in Turneffe Atoll, Belize from February to July 2022 (OCE-PRF: Drivers of phenotypic diversity and adaptation in asexually propagating coral populations)

We sought to investigate the role of genetic, intra-clonal, and environmental variation in driving variation in fitness-related traits in the Caribbean thin finger coral, Porites divaricata (Taxonomy ID: 262287). We conducted a reciprocal transplant experiment whereby fragments from individual coral colonies of known genetic background were transplanted to three sites from February to July 2022. These sites included two mangrove sites and one reef site at Calabash Caye, Turneffe Atoll, Belize. Prior to and post-transplanting, fragments were measured to determine growth rate over this time. Coral fragments were also photographed to determine red channel intensity, which serves as a proxy for chlorophyll density.

This dataset contains environmental information about each transplanted site over this time period, based on loggers that recorded temperature and light levels. This data was collected by scientists at the University of Texas at Austin and the University of Belize.

A related dataset contains the measures of these two coral traits (coral fragment growth and chlorophyll density (red channel intensity)) for each coral individual and also contains metadata about the genotype, origin site, transplanted site, rope at transplanted site, and age.

[Coral Transplant Survival Data] -  (NSF-BSF: Assessing the mechanisms of molecular and morphological adaptation by corals to extreme environments)

In November 2022, colonies of the coral Porites astreoides were collected from two sites off Little Cayman, Cayman Islands, at two depths: shallow (10 m) and mesophotic (45 m). Each colony was bisected, and a cross-depth transplantation experiment was conducted in which one half of each colony was returned to its native depth, while the other half was transplanted to the alternate depth. At each site, light (PME miniPAR) and temperature (HOBO ProV) loggers were deployed to monitor environmental conditions. After a 9-month period, all fragments were recovered and evaluated for survival and overall health status. This dataset represents the survival data for all colonies that were cross-transplanted, providing insight into the adaptive capabilities of corals to differing environmental conditions.

12 corals were selected with Coralliophila violacea.  A random snail was selected, and a similar location identified on the coral for comparison.  At each location, a 20cm by 20cm plexiglass plate was placed against the coral, and 20 randomly selected depth measurements taken.  The variance of those measurements is reported.  A nail was then hammered into the coral at each location, and the length recorded.   After 1 year, the corals were revisited, and the measurements repeated to calculate change in nail length (coral linear extension) and change in morphology (change in variance of depth measurements).

[Corals on ship and plane wrecks] - Community composition of benthic invertebrates on underwater cultural heritage and coral reefs from Palau aquired May to November 2022 (Collaborative Research: How do selection, plasticity, and dispersal interact to determine coral success in warmer and more variable environments?)

Ships, planes, and other vessels that come to rest on the seafloor introduce metals to the marine environment. Underwater cultural heritage (UCH) sites become important habitats for sessile invertebrates, but the materials they are made from can impact the composition of species living on them. We collected and analyzed images from three sites in Palau (two shipwrecks and one plane wreck from WWII) along with directly adjacent (1 – 5 m away) naturally-occurring coral reefs. We collected images of the sessile invertebrate fauna at each site using a Nikon D850 camera with a wide-angle lens, a GoPro Hero 7 with a wide-angle lens, and two Olympus TG-6 cameras. Wide-angle photography was used to record adult corals or other sessile invertebrates (≤ 5 cm diameter) in quadrats (0.34 ± 0.01 m2, mean ± SE). Olympus cameras were used for macro photography of young coral recruits (< 5 cm diameter), with each recruit being photographed individually to enable identification. Images were used to visually identify and count sessile invertebrates living on each wreck and the adjacent coral reefs. Coral species were identified to the genus level by comparison to published guides. Other sessile invertebrate species were identified to broad taxonomic categories (e.g., wire coral, sponge, tube worm).

[COVID Galapagos Megafauna Sizes] - Body size measurements of megafauna species at 6 sites after the 2020 COVID lockdown in the Galapagos Islands from 2020-2021 (Galapagos diver disturbance project) (RAPID: Illuminating the effects of a COVID-19 elimination of diver disturbance on reef fish behavior, distribution and ecosystem functioning in the Galapagos Marine Reserve)

The effect of changing levels of scuba diver disturbance, from a low during the 2020 COVID 19 lockdown to normal levels nearly a year later (July - August 2021) on the body sizes of  6 species of marine megafauna (sharks, sea lions and rays) was sampled to test the hypothesis the megafauna community would differ between the lockdown and post-lock down period 1 year later.  These data are from the period after the COVID 19 lockdown in July-August 2021.

The presence and size of the megafauna was recorded by extended duration video cameras that recorded from a fixed position at 12-15 m depth at each of the 6 sites. These were GoPro7 cameras in an aluminum housing with a battery pack to enable 6-8 hrs of continuous video recording. All megafauna species seen within 5 meters distance from the camera were identified to species. Total body lengths of megafauna were estimated within 5 cm increments by comparing them to known size indicators in the videos.

These data were collected by Drs Robert Lamb, Jon Witman and Franz Smith. Rebecca Ward-Diorio worked up the data from the GoPro files.  The GoPro file names are provided for reference. Day trips to support scuba based research on board the MV Valeska, a 14 m long fiberglass boat. Various trips between October 1, 2020 to August 31, 2021, with Jon Witman as Chief Scientist

[Cr concentration and isotope data using dissolved Cr and different Cr species from RR1805] - Chromium (Cr) concentration and isotope data determined using dissolved Cr and different Cr species from samples collected on R/V Roger Revelle cruise RR1805 in April-May 2018 (Cr Isotope Oceanography of the Eastern Tropical North Pacific Ocean)

Changes in chromium (Cr) isotope ratios due to fractionation between trivalent (Cr(III)) and hexavalent (Cr(VI)) are being utilized by geologists to infer oxygen conditions in past environments. But there is little information available on Cr in the modern ocean to ground-truth these inferences. Transformations between the two chromium redox species are important processes in oceanic Cr cycling. Here we present profiles of hexavalent and trivalent Cr concentrations and stable isotope ratios from the Eastern Tropical North Pacific (ETNP) oxygen deficient zone (ODZ) which support theoretical and experimental studies that predict that lighter Cr is preferentially reduced in low oxygen environments, and that residual dissolved Cr becomes heavier due to removal of particle-reactive Cr(III) on sinking particles. The Cr(III) maximum dominantly occurs in the upper portion of the ODZ, implying that microbial activity (dependent on the sinking flux of organic matter) may be the dominant mechanism for this transformation, rather than a simple inorganic chemical conversion between the species depending on the redox potential.

[Cr concentration and isotopic composition of Cr(III) and Cr(VI) in the ETNP from RR1804-05 and KM1919-20] - Chromium concentration and isotopic composition of Cr(III) and Cr(VI) in the Eastern Tropical North Pacific from samples collected on R/V Roger Revelle and R/V Kilo Moana in April-May 2018 and Sept-Oct 2019 (Cr Isotope Oceanography of the Eastern Tropical North Pacific Ocean)

Understanding the cycling of chromium (Cr) and how chromium stable isotopes (δ53Cr) are altered in response to different processes in the modern ocean is important in our interpretation of marine sedimentary δ53Cr records, a promising redox proxy. Therefore, it is crucial to investigate the geochemical processes of Cr in reducing environments such as oxygen deficient zones (ODZs). In this study, we investigated the cycling of Cr in the Eastern Tropical North Pacific (ETNP) ODZ by analyzing the [Cr] and δ53Cr of total dissolved Cr and Cr(III). Our Cr(III) data at two inshore stations shows profile features and Cr reduction isotopic fractionation factor (-1.5‰) similar to an offshore station in a previous study. We also observed significant Cr scavenging signals in the upper 1000 meters (m) throughout the ODZ with an inshore-offshore variability in its magnitude. Specifically, anoxic bottom waters on the continental slope see the greatest Cr scavenging with heaviest δ53Cr (+1.85‰). Our estimates of the scavenged Cr isotopic composition are within error of the anoxic and euxinic marine sedimentary δ53Cr. This implies that the vertical transport of Cr to the seafloor and subsequent diagenesis may not generate significant isotopic fractionation for Cr. This is the first thorough investigation into the Cr cycling in the ETNP ODZ and demonstrated promising usage of marine sedimentary δ53Cr as a redox proxy for ancient oceans.

In the ODZ, oxygen is consumed by degrading sinking particles and reaches extremely low levels (too low to support aerobic life) from 100m to 800m depth. However, microbes that can use other oxidants such as nitrate to metabolize organic carbon live there, and we showed that they also convert soluble anionic chromate Cr(VI) to cationic Cr(III), about half of which is scavenged onto sinking particles and removed to the seafloor. This reduction is accompanied by preferential reduction of light Cr isotopes, so the Cr(III) is 1.3‰ lighter than the source Cr(VI). The removal of part of this light Cr(III) by scavenging leaves the residual total Cr heavier than the source Cr. The analyzed samples listed here were chosen to be from the center and margins of the ETNP ODZ and over extremely reducing continental margin sediments.

[Cryptic CH4 Cycling] - Biogeochemical data on cryptic methane cycling in hypersaline sediments of the Carpinteria Salt Marsh Reserve, California from sampling in 2019 (Deciphering the Cryptic Cycling of Methane in Sediments of a Coastal Wetland)

Methylotrophic methanogenesis occurring within sulfate-rich zones of coastal and marine sediments is functionally linked to anaerobic methane oxidation (AOM), together constituting a cryptic methane cycle. This investigation presents data on such cryptic methane cycling across a land-to-sea transect comprising four sampling sites within the Carpinteria Salt Marsh Reserve (CSMR) in southern California, USA: two brackish, one marine, and one hypersaline. Surface sediments (upper 20 cm) were examined using geochemical profiling and radiotracer incubation experiments employing 35S-labeled sulfate, 14C-labeled monomethylamine, and 14C-labeled methane.

Methane concentrations in sediment porewater were generally low (3–28 µM) across all sites, except at the marine station, where levels increased with depth, reaching up to 665 µM. Methane production from monomethylamine was detected throughout the depth profiles at all stations, with estimated rates ranging from sub-nanomolar to nanomolar per cubic centimeter of sediment per day. AOM, quantified via 14C-CH₄ tracer, co-occurred with methylotrophic methanogenesis at each station, exhibiting activity levels between 0.03 and 19.4 nmol cm⁻³ d⁻¹.

Porewater chemistry revealed elevated concentrations of sulfate and dissolved iron across all sites. Sulfate levels (9–91 mM) remained sufficiently high to support sulfate reduction, which showed activity levels from 1.5 to 2,506 nmol cm⁻³ d⁻¹. Vertical profiles of sulfide and Fe(II) suggested a geochemical shift along the transect—from iron-dominated reduction at the brackish stations to sulfate-dominated reduction at the marine and hypersaline stations. AOM activity overlapped with zones of sulfate reduction and Fe(II) enrichment, indicating that methane oxidation may be coupled to both sulfate and iron reduction across all sampling locations.

[CSIA of gelatinous zooplankton] -  (Resolving vertical trophic linkages between surface and deep pelagic food webs)

We estimated the trophic positions of abundant gelatinous zooplankton (chaetognaths, cnidarians, ctenophores, molluscs, and pelagic tunicates) in the southern California Current Ecosystem using stable carbon and nitrogen isotope analysis. Gelatinous zooplankton were collected on four research cruises on the R/V Sally Ride and R/V Roger Revelle between 2020 and 2023 and from 0 to 3,000 m depth using a 10 m2 Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS). 561 samples of gelatinous zooplankton from 13 taxonomic groups were chosen for bulk tissue stable isotope analysis. An additional twenty samples from seven gelatinous genera were chosen for nitrogen compound-specific isotope analysis of amino acids because they were abundant across our region and represented a range of hypothesized feeding guilds and depth habitats (0 – 1,025 m). Gelatinous zooplankton were briefly thawed to remove visible gut contents using forceps and a scalpel. Samples were then lyophilized and homogenized. To ensure sufficient sample mass for stable isotope analysis, samples often contained multiple individuals from the same net, taxonomic group, and size class. The number of individuals per sample was typically fewer than 100, with a larger number of individuals pooled for some samples of Pantachogon spp. and Hormiphora spp. Samples were processed for nitrogen compound-specific isotope analysis at the Laboratory for Marine Organic Isotope Geochemistry at the University of Miami. This dataset includes the nitrogen compound-specific isotope values of amino acids for each gelatinous zooplankton sample and the sample's estimated trophic position.

[CTD and prey size data in Northern California Current 2022] - CTD summary and prey size data for five mucous mesh grazer species collected during R/V Sikuliaq Cruise SKQ202204S and R/V Marcus G. Langseth Cruise MGL2207 in the Northern California Current in Mar and Jul 2022 (Collaborative Proposal: Are all cell surfaces the same? The effects of particle surface property on predator-prey interactions in the microbial loop)

Mucous mesh grazers including pelagic tunicates and thecosome pteropods play a key role in oceanic food webs. Using their fine mucous meshes, these pelagic grazers ingest a wide range of planktonic prey and link pelagic and benthic marine ecosystems. Characterizing the diet of this group is central to fully understanding marine food webs and developing accurate food web models.

Microscopy has largely been supplanted by other methods, but it remains valuable for its precision in determining cell size and morphology, which are key to characterize the diet and feeding mechanics of grazers. In this study, we use environmental scanning electron microscopy (ESEM) to examine the gut contents of several mucous mesh grazers from the Northern California Current (NCC) including Dolioletta gegenbauri, Thetys vagina, Pegea socia, Pyrosoma atlanticum, and Limacina helicina. Our findings provide size and taxonomic resolution of the prey of these mucous mesh grazers and expands the known prey size range for some species. In the results paper, we also discuss the advantages of using microscopy, including insights into prey morphology and integrity, which enhances our understanding of feeding selectivity, prey defenses, and the fate of grazed plankton in marine ecosystems. Our results reinforce the significant predatory role of mucous mesh grazers in planktonic ecosystems and food webs.

This dataset includes size measurements of prey items found in the guts of each gelatinous grazer species which were collected and processed in the NCC over two sampling seasons and oceanographic research cruises, as well as background oceanographic data for these stations. The dataset includes collection metadata, CTD summary data, image analysis metadata, grazer species information, prey ids, and prey counts.

[CTD Composite Profiles] - Time series composite CTD profiles from R/V Hermano Ginés cruises in the Cariaco Basin from 1995 through 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. During each cruise, a minimum of four hydrocasts were performed to collect a suite of core monthly observations. We conducted separate shallow and deep casts to obtain a better vertical resolution of in-situ Niskin-bottles samples for chemical observations, and for productivity, phytoplankton, and pigment observations. One CTD composite profile was created for each cruise by stitching together the sections of the different cruise's CTD profiles at the depth interval where water samples were obtained. CTD\u2019s Salinity, Oxygen, and Fluorescence where calibrated with in-situ measurements. The composite CTD profiles dataset is a complement of the hydrographic time series data obtained with the Niskin Bottle Samples (https://www.bco-dmo.org/dataset/3093). The following sections describe the methods used in collecting the core observations at the CARIACO station.

[CTD data from LMG1110] - CTD data from ARSV Laurence M. Gould LMG1110 in the Southern Ocean from November to December 2011 (Salp_Antarctic project) (Population ecology of Salpa thompsoni based on molecular indicators)

This is from the cruise report (see LGM1110 deployment page for link) and
particulary pertains to the Fluorescence data that were collected:

\Preliminary CTD Results: A total of 20 CTD stations were occupied and
sampled during the cruise. Hydrographic data were collected in all sampling
regions of the study. Casts were sent to the shallower of 1,000 m or 5-10 m
above the bottom. The primary fluorometer was mis-calibrated (had the wrong
scale factor in the calibration/processing file), so fluorescence data from
the first four (or five) stations (Stns #22, #7, #8, #11) had to be re-
processed with the correct scaling factor. Examination of the *.cnv file
showed which casts had the miscalibrated data, as the max reading for
fluorescence was ~ 0.05 mg/m3. For nearly every other station, maximum
fluorescence readings were > 1.0 mg/m3. A secondary fluorometer was added to
the CTD rosette between Stns #11 and #12, which verified that the issue was
with the scale factor in the CTD processing software.\

The data that are served have warnings about fluorescence numbers in the
headers of the casts at Stations 22, 7, 8 and 11.

Variables that were part of the data that have been rendered invisible from
the data online are: Elapsed time in seconds, modulo error count (always
zero), and nbin (number of scans per bin). Those numbers are available upon
request.
