[GTseq KW 2015-2017] - GTseq DNA sequencing of Kelletia kelletii collected in California, USA and Baja, Mexico from 2015 to 2017 (Collaborative Research: RUI: Combined spatial and temporal analyses of population connectivity during a northern range expansion)

Summary:
Climate-driven warming and changes in major ocean currents enable poleward transport and range expansions of many marine species. Here, we report the population genetic assignment of post-dispersal recruits to pre-dispersal natal source locations for the gastropod Kellet's whelk (Kelletia kelletii), a commercial fisheries species and subtidal predator with top-down food web effects, whose populations have recently undergone climate-driven northward range expansion.

This dataset includes sample id, collection site and year, tissue type, length, and extraction information for samples sequenced. Samples were collected between 2015-2017. We genotyped 2,874  individuals from 24 locations across the species' entire biogeographic range using 305 genotyping-in-thousands by sequencing (GT-Seq) loci. Analysis shows a large contribution of 1-year old recruits from the historical range to the expanded range, variable post-settlement survival of those recruits in the expanded range in relation to their natal origin, and that El Niño Southern Oscillation may play a role in long distance dispersal.

[Gulf of Alaska Al and Mn - Surface Samples] - Dissolved aluminum (Al) and manganese (Mn) and total dissolvable Al and Mn from surface water samples collected during three cruises in 2010 in the northern Gulf of Alaska (US GEOTRACES Pacific Section-Shipboard Al, Mn and Fe)

Summary:
Water samples were collected along a transect during three cruises in 2010 (7-9 April, 5-7 May, and 27-29 July) in the northern Gulf of Alaska, from the mouth of the Copper River to about 50 km past the shelf break. Surface samples were collected by underway pumping using Teflon-lined tubing, using a method modified from Vink et al. (2000). Filtered dissolved metal surface samples were collected using a 0.45 µm in-line Acropore filter under N₂ pressure. Water samples were processed in the shipboard clean lab within three hours of collection. Dissolved samples were filtered using acid-washed 0.45 µm Pall-Supor filters. All samples were acidified to pH 1.8 using Seastar grade HCl within 3 days and stored for 5 years before analysis.

Filtered samples were analyzed for dissolved Al and unfiltered samples were analyzed for total dissolvable Al using Flow Injection Analysis (Resing and Measures 1994) using fluorescent detection of lumogallion. Filtered samples were analyzed for dissolved Mn and unfiltered samples were analyzed for total dissolvable Mn according to the method of Resing and Mottl (1992), which uses spectroscopic detection of leuchomalachite green.

Summary:
Water samples were collected along a transect during three cruises in 2010 (7-9 April, 5-7 May, and 27-29 July) in the northern Gulf of Alaska, from the mouth of the Copper River to about 50 kilometers past the shelf break. Vertical profiles were collected using Teflon-lined Niskin bottles attached to a Spectra™ (Dyneema) line and triggered using Teflon-lined messengers. Additionally, profiles of salinity, temperature, fluorescence, and turbidity were measured with a Seabird SBE16 CTD, deployed at the same time as the collection of the subsurface water samples. Water samples were processed in the shipboard clean lab within three hours of collection. Dissolved samples were filtered using acid-washed 0.45-micrometer Pall-Supor filters. All samples were acidified to pH 1.8 using Seastar grade HCl within 3 days and stored for 5 years before analysis.

Filtered samples were analyzed for dissolved aluminum (Al) and unfiltered samples were analyzed for total dissolvable Al using Flow Injection Analysis (Resing and Measures 1994) using fluorescent detection of lumogallion.

[Gulf of Alaska copepods: annotated transcriptomes] - Annotated de novo transcriptomes generated from six co-occurring species of calanoid copepods from the R/V Tiglax TXF18, TXS19, TXF15, TXF17 in the Gulf of Alaska from 2015-2019 (Collaborative Proposal: Optimizing Recruitment of Neocalanus copepods through Strategic Timing of Reproduction and Growth in the Gulf of Alaska)

Summary:
The dataset includes the annotation files of nine high-quality de novo transcriptomes generated from shotgun assemblies of short-sequence reads. The species are ecologically-important members of sub-arctic North Pacific marine zooplankton communities. The de novo assemblies included one generated several years ago plus eight new ones generated from six co-occurring species of calanoid copepods in the Gulf of Alaska. The transcriptomes include the first published ones for Neocalanus plumchrus, Neocalanus cristatus, Eucalanus bungii and Metridia pacifica and three for Neocalanus flemingeri and two for Calanus marshallae. Total RNA from single individuals was used to construct gene libraries that were sequenced on an Illumina Next-Seq platform. Short-sequence reads were assembled with Trinity software and resulting transcripts were annotated using the SwissProt database with additional functional annotation using gene ontology terms and enzyme function. The annotations files are the first ones published for these species. The integrated dataset can be used for quantitative inter- and intra-species comparisons of gene expression patterns across biological processes using the annotations.

These data are further described in the following publications: Hartline, et al. (2023) (DOI: 10.1038/s41597-023-02130-1), Roncalli, et al. (2022) (DOI: 10.1111/mec.16354), and Roncalli, et al. (2019) (DOI: 10.1038/s42003-019-0565-5)

The JOMEX experiment ran from 26 June to 10 July 2019 and the mesocosms were divided into three treatment groups: 1) three control mesocosms with no humic substances or nutrients added, 2) three humic-amended mesocosms with only humic substances added to a final concentration of 2 mg L−1 in each mesocosm and three humic+nutrients-amended mesocosms with humic substances (2 mg L−1 final concentration) and 3) NH4Cl and KH2PO4 (80 μg L−1 N and 20 μg L−1 P final concentrations) added.

Surface (1 m) water samples for the LightCycle experiments were collected from one each of control, humic-amended and humic+nutrients-amended mesocosms, immediately after the amendment (day 1) and 2, 5, 7, 9 and 12 days after the amendment (days 3, 6, 8, 10 and 13). These water samples were filtered with 0.2 mm filters and irradiated under a solar simulator.

CDOM absorbance at different irradiation time points were measured for these experiments using a Shimadzu UV-2501PC UV-VIS recording spectrophotometer or an Agilent 8453 UV-visible Spectrophotometer, and converted to Naperian absorption coefficients.

The measurements of CDOM absorption and the subsequent calculation of CDOM fading (decrease in absorption) offered clues to the degradation of CDOM, and provided insights into the potential of photochemistry to remove added terrestrial dissolved organic matter (DOM) and the interactions of DOM photochemistry with eutrophication in this Baltic Sea system, where there are increasing concerns that climate change and anthropogenic activities can lead to increased terrestrial input of humic substances to surface waters and browning of surface waters.

These data were collected by Kun Ma and Jay Brandes of the Skidaway Institute of Oceanography, Department of Marine Sciences, University of Georgia.

[gut equal] - Microsphere counts from gut samples for equal microsphere concentration incubations (Collaborative Proposal: Are all cell surfaces the same? The effects of particle surface property on predator-prey interactions in the microbial loop)

Summary:
Cell surface properties can strongly mediate microbial interactions with predators in soil and host-pathogen systems. Yet, the role of microbial surface properties in avoiding or enhancing predation in the ocean remains a research frontier. Appendicularians are globally abundant marine suspension feeders that capture marine microorganisms in a complex mucous filtration system. We used artificial microspheres to test whether the surface properties of prey particles influenced selection by the appendicularian, Oikopleura dioica . Across microsphere sizes (0.5, 1, 2 and 3 µm) and concentrations (~103-106 particles ml-1), which were varied to represent realistic microbial communities, carboxylate- and amine-modified particles were handled differently by the appendicularians. The carboxylate-modified particles were enriched in the gut while the amine-modified particles were enriched in the mucous filters, leading to different particle fates.

Summary:
Size-fractionated particles were collected via in-situ filtration aboard the R/V Kilo Moana on four separate cruises (KM2210, KM2305, KM2306, and KM2311) at the Hawaii Ocean Time-Series study site, Station ALOHA, between 2022-08-30 to 2023-08-14. Marine particulate trace element concentrations were assessed via magnetic sector inductively coupled plasma mass spectrometry (ICP-MS). Many of these trace elements are required by marine organisms and can act as tracers of oceanographic processes. These data were used as part of the Hawaii Aerosol Time-Series (HATS) project to observe how seasonally variable atmospheric deposition of aerosol trace elements to the ocean impacts the compositional inventories of size-fractionated upper water column particulate trace elements.

[HATS Total Aerosols] - Weekly integrated bulk total aerosol trace element concentrations from the Hawaii Aerosol Time-series during January 2022 to October 2023 (Hawaii Aerosol Time-Series (HATS):Quantifying Marine Dust Deposition and Composition in an Oligotrophic Gyre)

Summary:
This study aimed to quantify seasonal aerosol trace element fluxes and evaluate their variability and potential sources over a two-year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS), a sampling program at Makai Research Pier on O'ahu (21.32° N, 157.67° W), to collect weekly-integrated total suspended particle samples. Sampling was sector-controlled to collect when winds were onshore at a velocity of greater than 0.5 meters per second (m/s). The sampler was fitted with a GEOTRACES-style, custom-made manifold holding 12 acid-washed, 47-millimeter (mm) diameter Whatman-41 filters. Three filters were reserved for total digestion. The digestion procedure is a three-step process where the samples were sequentially acidified with concentrated double-distilled nitric acid, hydrofluoric acid, and hydrogen peroxide, heated to ~140 degrees Celsius (°C) on a hotplate overnight, and then taken to near dryness. Following the final dry-down, samples were brought up in 0.32 M optima HNO3 and then analyzed for a mix of primarily lithogenic and anthropogenically associated trace elements (including Al, Co, Cr, Cu, Fe, Mn, Ni, Pb, Ti, V, and Zn) via quadrupole inductively coupled plasma mass spectrometry (ICP-MS).

[Hawaiian sponge cryptofauna] - Specimen vouchers of sponges collected in a study of hidden sponge biodiversity within the Hawaiian reef cryptofauna conducted on Oahu, Hawaii from 2016 to 2018 (Testing the most striking tropical marine biodiversity gradient on the planet: does it hold for sponges?)

Summary:
Sponges are abundant and conspicuous on the reef surface in productive, continental reefs, but largely vanish from surveys of the oligotrophic reefs of Oceania. However, their diversity in the cryptobiota remains poorly characterized. Here, we explore the contribution of cryptobenthic sponges to overall sponge diversity on 1,750 square meters of reef habitat in Kāne'ohe Bay and Waimanalo in the island of O'ahu, Hawai'i. We also assessed cryptic sponges using 15 square meters of Autonomous Reef Monitoring Structures (ARMS) deployed in this same area. We used integrative taxonomy combining morphology, COI and 28S barcoding to delineate and track species, most of which are poorly known or undescribed. We documented 186 OTUs, 150 of which are new records for the Hawaiian Islands, increasing the known sponge fauna of Kāne'ohe Bay by 3.5 fold, and that of the Hawaiian Islands by 2.5 fold. More than ¾ of the sponge OTUs were cryptobenthic. Reef sampling provided access to 31% (44 OTUs), whereas 52% (75 OTUs) were retrieved exclusively from ARMS. These results illustrate that the interstices of ARMS units provide suitable habitat for settlement of cryptobenthic sponges that would otherwise be impossible to access through traditional field surveys. Tracking species with provisional names, using integrative species delineation anchored to vouchers, images, and DNA barcodes provides a powerful approach for working with such a poorly understood fauna.

[Headwater Terrestrial Organic Matter] - Impacts of Terrestrial Organic Matter on Methanogenic Archaea in Littoral and Pelagic Sediments of the Mississippi River Headwaters from June to September 2020 (Cyanos Great Lakes Project) (Collaborative Research: Cyanobacteria, Nitrogen Cycling, and Export Production in the Laurentian Great Lakes)

Summary:
Terrestrial organic matter (tOM) plays a key role in aquatic ecosystems, influencing carbon cycling and greenhouse gas emissions. Here, we investigate how tOM affects methane production in littoral and pelagic sediments from the Mississippi River headwaters using a controlled microcosm approach. Contrary to expectations, tOM additions consistently enhanced methane production across both sediment types, with no significant differences between littoral and pelagic zones. Methane generation was mediated by specific sediment microorganisms—primarily methanogens and lignocellulose-degrading bacteria—which exhibited similar responses across habitats.

Sequencing data associated with this paper is available on NCBI through the project PRJNA1164797: Impacts of Terrestrial Organic Matter on Methanogenic Archaea in Littoral and Pelagic Sediments of the Mississippi River Headwater.

Our results highlight the contribution of cytochrome-containing methanogens and their syntrophic interactions with fermentative bacteria, underscoring the importance of microbial community composition in regulating sediment methane dynamics. These findings suggest that increasing tOM loads to freshwater systems could have broader implications for methane emissions, driven by specific microbial interactions.

[Heat priming in Nematostella vectensis: Development of larvae past the planula stage] - Data pertaining to the development of larvae past the planula stage from experiments investigating heat priming in Nematostella vectensis (Influence of environmental pH variability and thermal sensitivity on the resilience of reef-building corals to acidification stress)

Summary:
Across diverse taxa, sublethal exposure to abiotic stressors early in life can lead to benefits such as increased stress tolerance upon repeat exposure. This phenomenon, known as hormetic priming, is largely unexplored in early life stages of marine invertebrates, which are increasingly threatened by anthropogenic climate change. To investigate this phenomenon, larvae of the sea anemone and model marine invertebrate Nematostella vectensis were exposed to control (18 °C) or elevated (24 °C, 30 °C, 35 °C, or 39 °C) temperatures for 1 hour at 3 days post-fertilization (DPF), followed by return to control temperatures (18 °C). The animals were then assessed for growth, development, metabolic rates, and heat tolerance at 4, 7, and 11 DPF. To investigate a possible molecular mechanism for the observed changes in heat tolerance, the expression of heat shock protein 70 (HSP70) was quantified at 11 DPF. The study's findings suggest heat priming may augment the climate resilience of marine invertebrate early life stages via the modulation of key developmental and physiological phenotypes, while also affirming the need to limit further anthropogenic ocean warming.

[Heat stress experiment data] - Proportions of healthy, pale, bleached, and dead Orbicella faveolata recruits over time during a heat stress laboratory experiment conducted in 2018 and 2019, corresponding to proportions of different symbiont genera hosted (Collaborative Research: Assessing the changing symbiotic milieu on Caribbean coral reefs under climate change: magnitude, tradeoffs, interventions, and implications)

Summary:
Proportions of healthy, pale, bleached, and dead Orbicella faveolata recruits over time during a heat stress experiment, corresponding to proportions of different symbiont genera hosted.

These data correspond to research presented in Williamson et al. (2021), published in Coral Reefs and funded in part by the NSF project "Symbiont Shifts on Reefs". They were used to test if Orbicella faveolata recruits could establish symbiosis with D. trenchii supplied by nearby “donor” colonies and examined the resulting ecological trade-offs to evaluate early Symbiodiniaceae manipulation as a scalable tool for reef restoration. We exposed aposymbiotic recruits to 29 °C or 31 °C and to fragments of Montastraea cavernosa (containing Cladocopium ITS2 type C3) or Siderastrea siderea (containing D. trenchii). Next, a subset of recruits were exposed to a 60-day heat stress. These data include survivorship and symbiont acquisition rates, symbiont identity and density data (derived using qPCR), polyp area measurements, and scoring of bleaching and survivorship during a heat stress experiment. Overall, proportion of D. trenchii hosted was negatively correlated with polyp size and symbiont density, indicating a trade-off between growth (of both host and symbiont) and heat tolerance. These findings suggest that, while donor colonies may be effective sources for seeding coral recruits with thermotolerant symbionts, practitioners will need to balance the likely benefits and costs of these approaches when designing restoration strategies.

[High Sensitivity DIP] - Global distribution of phosphate using high sensitivity techniques from data aggregated from many studies between 1988-2017 (Convergence: RAISE: Linking the adaptive dynamics of plankton with emergent global ocean biogeochemistry)

Summary:
Surface ocean phosphate is commonly below the standard analytical detection limit (~100 nM) leading to an incomplete picture of the global variation and biogeochemical role of phosphate. This dataset represents a global compilation of phosphate measured using high-sensitivity methods including magnesium induced precipitation (MAGIC), liquid waveguide cell (LWCC), and solid phase extraction (SPE) methods. We compiled data from 42 major cruises covering all oligotrophic regions using high-sensitivity P measurements. The dataset covered a total of 50591 samples including 41747 samples from the upper 30 m. The compilations revealed several previously unrecognized low-P areas and clear regional biases. Our study demonstrates the importance of accurately quantifying nutrients for understanding the regulation of ocean ecosystems and biogeochemistry now and under future climate conditions.

[High-Frequency CO2-system observations from a moored sensor in the York River] -  (Collaborative Research: Multiple Stressors in the Estuarine Environment: What drives changes in the Carbon Dioxide system?)

Summary:
These are CO2-system data from a moored sensor in the York River, a tributary of the Chesapeake Bay. Temperature, salinity and pH were acquired hourly over two deployments lasting several months. Sensor data were then averaged to 24-hour resolution. Data were calibrated with discrete dissolved inorganic carbon (TCO2) and alkalinity samples analyzed at the Virginia Institute of Marine Science, following standard procedures. The pH sensor data were then combined with salinity data, and a relationship between alkalinity and salinity, to compute the remaining CO2-system parameters (TCO2, CO2 partial pressure (pCO2), and saturation state of aragonite. There is one file for each deployment (D1, and D2); the data are in a comma-separated (csv) format. Hourly measured temperature, salinity, and pH are given, as well as derived alkalinity, TCO2, pCO2, and saturation state of aragonite are included. Units are in the first row of each file.

[Hog reef coral core trace metals] - Trace metal ratios from four coral skeletons from three coral species (Diploria labyrinthiformis, Pseudodiploria strigosa, Orbicella franksi) extracted from Hog Reef in Bermuda, collected in August of 2016. (Drivers of coral and reef-scale calcification in the North Atlantic)

Summary:
These data include trace metal ratios from four coral skeletons from three coral species (Diploria labyrinthiformis, Pseudodiploria strigosa, Orbicella franksi) extracted from Hog Reef in Bermuda. The cores were collected in August of 2016 using small boats from the Bermuda Institute of Ocean Sciences (BIOS). Trace metal ratios were measured at intervals of 200 micrometer in each coral core ranging from the top to a core depth of 36305 to 79625 micrometer using LA-ICP-MS. Understanding seasonal, interannual, and long-term variations in trace metal ratios incorporated into coral skeletons has the potential to refine our understanding of environmental drivers of coral calcification. These data were collected by Dr. Andreas Andersson, Scripps Institution of Oceanography, University of California San Diego, and Dr. Travis Courtney, University of Puerto Rico, Mayagüez Campus.

[Holothuria floridana viromes] - Viral metagenomic investigation of the Caribbean echinoderm Holothuria floridana collected in Marathon, Florida in Sep 2023 (Exploring the role of boundary layer microbial remineralization in flavivirus-host dynamics)

Summary:
Echinoderms play crucial roles in coral reef ecosystems, where they are significant detritivores and herbivores. The phylum is widely known for its boom and bust cycles, driven by food availability, predation pressure and mass mortalities. Hence, surveillance of potential pathogens and associates of grossly normal specimens is important to understanding their roles in ecology and mass mortality. We performed viral surveillance of the coral reef echinoderm Holothuria floridana (urn:lsid:marinespecies.org:taxname:210900), using metagenomics. Grossly normal H. floridana specimens were collected from a reef in Florida. Viral metagenomes were assembled and aligned against viral genomes and protein encoding regions. Metagenomic reads and previously sequenced transcriptomes were further investigated for putative viral elements by Kraken2. H. floridana yielded viral taxa similar to those found in other sea cucumbers, including Pisoniviricetes (Picornaviruses), Ellioviricetes (Bunyaviruses), and Magsaviricetes (Nodaviruses). This dataset includes the accession information for the sequences performed and archived at the National Center for Biotechnology Information (NCBI) Sequence Read Archive.

[HOT CTD Profiles] - Two decibar-averaged CTD profiles from the Hawaii Ocean Time-Series cruises from 1988-2023 (HOT project) ([Current] Hawaii Ocean Time-series (HOT): 2023-2028;  [Previous] Hawaii Ocean Time-series (HOT): Sustaining ocean ecosystem and climate observations in the North Pacific Subtropical Gyre)

Summary:
The dataset includes CTD data collected by the Hawaii Ocean Time-series (HOT) ocean measurement program on cruises taken from October 1988 to December 2023, during the monthly expedition to Station ALOHA. HOT CTD data are collected using a SeaBird CTD 9-11 (9-11 Plus with dual sensors as of HOT-54) at the maximum sampling rate of 24 samples per second (24 Hz). They are screened for errors and processed to 2-dbar averages. The majority of the sampling effort, approximately 60-72 h per standard HOT cruise, is spent at Station ALOHA. High vertical resolution environmental data are collected with a Sea-Bird CTD having external temperature (T), conductivity (C), dissolved oxygen (DO) and fluorescence (F) sensors and an internal pressure (P) sensor. A Sea-Bird 24-place carousel and an aluminum rosette that is capable of supporting 24 12-L PVC bottles are used to obtain water samples from desired depths. The CTD and rosette are deployed on a 3-conductor cable allowing for real-time display of data and for tripping the bottles at specific depths of interest.
