[Virus production at a hydrothermal vent site] - Virus and prokaryote abundances from experiments conducted with samples collected at a hydrothermal vent site by ROV SuBastian during R/V Falkor (too) expedition FKt230627 along the East Pacific Rise in July of 2023 (The Underworld of Hydrothermal Vents)

Summary:
We used the virus-dilution technique to quantify lytic virus production at nine sites across vent, sub-vent, and non-vent habitats along the East Pacific Rise during expedition FKt230627 aboard R/V Falkor(too). This technique leverages the density-dependent nature of viral infection, preventing new infections by dilution. Samples were collected via ROV SuBastian, sequentially filtered to remove larger particles, and concentrated using tangential-flow filtration. Duplicate incubations were set up with prokaryotic concentrate and virus-free water, pressurized to 250 bar, and incubated in the dark at in situ temperatures for 30 hours. Subsamples were taken every six hours for enumeration of prokaryotes and viruses via flow cytometry. Parallel experiments were conducted at surface pressure to assess the impact of pressure on virus production rates. The methodology ensures observed increases in viral abundance are due to pre-existing infections. The experiments were conducted aboard R/V Falkor(too) between 5-22 July 2023 by Tinkara Tinta and Nicole Krause. Prokaryotes and viruses were enumerated flow-cytometrically back in the lab by Christian Winter.

[Water Column Dissolved and Total Dissolvable Metal Concentrations, Hawaii Ocean Timeseries 2020-2023] - Water column dissolved and total dissolvable metal concentrations from Hawaii Ocean Timeseries (HOT) R/V Kilo Moana cruises at station ALOHA, North Pacific Subtropical Gyre, from December 2020 to November 2023 (Quantifying Iron Turnover in the Upper Ocean via Time-series Measurements at Station ALOHA)

Summary:
We collected and analyzed water samples for dissolved and total dissolvable trace metal concentration on Hawaii Ocean Time-series (HOT) cruises between December 2020 and November 2023. All samples were collected at Station ALOHA. Samples were collected using a trace metal rosette. Approx. 12 depth samples were collected for each cruise within the upper 350 m of the water column.

Dissolved metal measurements reflect samples filtered through a 0.2 micron filter. Total dissolvable metal measurements represent unfiltered samples. Both sample types were acidified for > 2 months after collection and metals were extracted via chelating resin (Nobias PA-1) and analyzed by inductively coupled plasma mass spectrometry at the University of Hawaii at Manoa using a Thermo Scientific iCAP-TQ mass spectrometer.

This dataset is part of a larger study focused on the cycling of trace metals in the North Pacific Subtropical Gyre, and is embedded within the HOT program.

Summary:
Dataset includes winter temperature logger data for a suite of embayments in the northeast Pacific. Data were collected as part of an NSF-funded project on invasive European green crab adaptation; loggers were placed in the shallow subtidal in areas determined by Washington Sea Grant's Crab Team to be good environments for green crabs. Loggers were placed by multiple collaborators without a fully standardized approach; metadata are incomplete but include all available information. Loggers used were iButtons and HOBO pendant loggers. Two loggers were placed at each site in the shallow subtidal with the goal that they were always submerged in water while deployed (i.e., not emersed). Logging frequency depended on the monitor type; iButtons captured water temperatures every 2.15 hours, and HOBO loggers recorded water temperature every 30 minutes over the winter. Deployment duration varied between years and sites, but typically ran from October - April.

[X-ray diffraction from seafloor sulfide deposits East Pacific Rise 9-10 North] - Synchrotron micro-probe X-ray diffraction data from seafloor sulfide deposits collected during cruise AT42-09 on the East Pacific Rise (EPR) in April 2019 (Collaborative Research: From hot to cold in the dark - shifts in seafloor massive sulfide microbial communities as physical and geochemical conditions change after venting ceases)

Summary:
Synchrotron micro-probe X-ray diffraction data were collected for seafloor sulfide deposits. Seafloor sulfide mineral samples were collected from hydrothermally active chimneys and inactive off-axis massive sulfide deposits at East Pacific Rise (EPR) 9.50°N in 2019-2021 on cruise AT42-09. Samples were collected using the HOV Alvin. Samples were placed in a positive-pressure glove bag flushed with N2 (g), sparged with N2, heat-sealed into mylar bags containing Anaeropaks, and stored at -20°C.

Epoxy embedded petrographic thin sections were created using these samples. Subsamples were dried for 24 hours under N2 (g), vacuum embedded in epoxy resin (Struers EpoFix Resin, 1L kit: Part #40200030) following manufacturer's guidelines, and cured under N2 (g) for 24 hours. Each epoxy-embedded sample was pre-cut using a wafering saw then sent to Spectrum Petrographics, Inc. (Washington, USA) for preparation as 30 micron thick, double-polished thin sections mounted on quartz slides using methods to limit sample exposure to water and ambient air. When not in use, thin-sections were stored under N2 (g) to limit oxidation. Thin sections were analyzed for X-ray diffraction at the X-ray Fluorescence Microprobe beamline "XFM", National Synchrotron Light Source II (NSLS II), Brookhaven National Laboratory, NY.

[Zonar Data, Zooglider BioSWOT-Med] - Zonar data for BioSWOT-Med Zooglider deployment in the Northwestern Mediterranean Sea, March-May 2023 (Zooglider assessment of zooplankton frontal gradients across the BIOSWOT-Med region)

Summary:
These data are based on deployment of the Scripps Zooglider in collaboration with the French-led BIOSWOT-Med study in the Northwestern Mediterranean Sea in Spring 2023.  This study was one of the Adopt-a-Crossover field studies carried out around the world in synchrony with the launch by NASA/CNES of the new SWOT satellite for enhanced ocean altimetry.  We deployed Zooglider on 30 March 2023 from Palma, Majora using a small craft, then navigated it remotely to the BIOSWOT-Med study region.  Initially Zooglider sampled to the east of Majorca and south of Menorca. Then we recovered Zooglider at sea, transported it to the center of an anticyclonic eddy north of Menorca, and redeployed it, navigating it from the eddy center across the eddy periphery.  We then recovered it at sea on 8 May 2023, for a total mission duration of 40 days.  Zooglider data were telemetered back to our server each time the vehicle surfaced and the data were immediately posted on our public website, available to all BIOSWOT-Med participants and any member of the general public.  The data archived here are the data recovered from the Zooglider at the end of the mission.  They include acoustic volume backscatter at 200 kHz and 1000 kHz.  Data were typically acquired in Zooglider dives between approximately 420 m depth and the sea surface, apart from initial and final Zooglider dives that were somewhat shallower.

[ZooProcess and Ecotaxa Output Along Physical Gradients from OAPS] - ZooProcess and Ecotaxa output from ZooSCANs of zooplankton collected along physical gradients during OAPS MOCNESS tows during R/V Oceanus northwest Atlantic 2011 cruise OC473 and R/V New Horizon northeast Pacific 2012 cruise NH1208 and imaged in 2021-2022 (Quantifying the drivers of midwater zooplankton community structure)

Summary:
This dataset consists of the imaging portion of the study described below and includes ZooProcess and Ecotaxa outputs from ZooSCANs performed of zooplankton collected during Multiple Opening-Closing Net and Environmental Sensing System (MOCNESS) tows during R/V Oceanus cruise OC473 in the Northwestern Atlantic in 2011 and R/V New Horizon cruise NH1208 in the Northeastern Pacific in 2012. It includes data for this project from Ecotaxa (export v1.0), an online machine-learning platform that assists in identifying organisms and particles.  The dataset also includes particle measurements generated by ZooProcess software. Day and night stations were sampled between 0 to 1000m depths from 35 to 50 N in the northwest Atlantic in 2011, and from 35 and 50N along CLIVAR line P17N in 2012. These representative subsamples of the formalin-preserved zooplankton community from each net were imaged in 2021 and 2022.

Project description: The objective of this study was to determine how environmental variables shape zooplankton community structure in the midwater. Our primary overarching hypothesis was that the abundance and size class distribution of the zooplankton community are decoupled and are influenced by different environmental variables. Furthermore, differences in zooplankton community composition and diversity in the observed distinct oceanic biogeographical provinces additionally influences both factors. Since zooplankton contributions to biogeochemistry are size dependent, standard descriptions of zooplankton community (biomass, which is a product of size and abundance) are insufficient to generate a predictive understanding of the role of zooplankton in biogeochemical cycles. The project uses particle imaging technology and metabarcoding of archived biological samples in conjunction with open access hydrographic data from two cruises conducted in the N. Atlantic and N. Pacific to test these hypotheses.

[ZooProcess and Ecotaxa Output for Zooplankton Mediated Aggregates] - ZooProcess and Ecotaxa output from ZooSCANs of zooplankton collected with MOCNESS tows during six R/V Atlantic Explorer cruises from 2021 to 2023 (Collaborative Research: Zooplankton mediation of particle formation in the Sargasso Sea)

Summary:
This dataset consists of ZooProcess and Ecotaxa outputs from ZooSCANs of plankton caught in the upper 600m using Multiple Opening-Closing Net and Environmental Sensing System (MOCNESS) tows during day- and night-time. It includes data for this project from Ecotaxa (export v1.0), an online machine-learning platform that assists in identifying organisms and particles. The dataset also includes particle measurements generated by ZooProcess software. These samples were collected and processed over two years, with three cruises a year to capture distinct seasons. The goal of this data was to assess high-resolution vertical distribution of zooplankton in order to distinguish diel vertical migrators from resident populations and to quantify contributions to particulate organic carbon flux via fecal pellet production.

Project description: The oceanic biological carbon pump refers to the export of dissolved and particulate organic carbon to the deep ocean, and it is a significant driver of atmospheric carbon uptake by the oceans. Evidence from long-term research carried out at the Bermuda Atlantic Time-series Study (BATS) site suggests that the spectrum of particles collected by gel-traps below the euphotic zone changes drastically below 150 m, which is attributed to resident populations of zooplankton that feed on vertically migrating zooplankton as well as sinking particles. The goals of this study are to investigate the role of different zooplankton taxa on both particle aggregate formation and in particle transformation, and to compare and characterize the particles generated by the zooplankton communities with those collected by particle traps.
