Seawater dissolved chromium concentration, redox speciation, and stable isotope composition in the North Pacific Ocean
<p>Dissolved seawater chromium concentrations, redox speciation, and stable isotope composition were measured on samples collected in the North Pacific Ocean. Samples were collected over diel cycles (2 for stations 1-5, 1 for station 6) on board the RV Kilo Moana cruise KM1713 from Seward Alaska to Honolulu Hawai’i. Sampling stations spanned the subarctic North Pacific (stations 1 & 2), the dynamic subarctic-subtropical convergence zone (stations 3 and 4) and the subtropical North Pacific (stations 5 and 6). Chromium was enriched from filtered samples by Mg(OH)<sub>2</sub> co-precipitation and analyzed by MC-ICP-MS using either isotope dilution (Cr redox speciation) or double spike methodology.</p>
Journey North - Gray Whale observations by volunteer community scientists across the Eastern Pacific Ocean (1997-2020)
This data package contains Gray Whale migration data consisting of 1,546 total observational reports from 1997 - 2020 across the Eastern Pacific Ocean. These data were collected by 163 community scientists for Journey North, a crowdsourced participatory science program of the University of Wisconsin-Madison Arboretum. The Journey North Gray Whale Project is a study of Gray Whale phenology conducted at broad spatial and temporal scales. Since 1997, community scientists have tracked the migration of Gray Whales (Eschrichtius robustus) through the Eastern Pacific Ocean. Observers also provide estimates of the number of whales sighted. However, observers do not follow standardized methods for counting species observed. Observers do not observe at set times of the day, do not repeat observations regularly, and are not required to provide the length of time during which a specified number of species observed were counted. Therefore, it is recommended that this dataset be analyzed to indicate presence not abundance. Researchers are encouraged to read the rich information provided by volunteers in their comments. These comments provide qualitative information about observational reports. Researchers are also encouraged to refer to submitted photographs that also provide context for observational reports. The Journey North Gray Whale Project dataset is hosted by the University of Wisconsin-Madison Shared Web Hosting Service.
North Pacific Subtropical Gyre RCLV Atlas (Version 2)
<p>This dataset tracks Rotationally Coherent Lagrangian Vortices (RCLVs) at an 8-day resolution in the North Pacific Subtropical Gyre region around Hawai’i. The ‘lat’ and ‘lon’ variables represent the center coordinates of the vortex, or the extremum of integrated relative vorticity. The contour boundaries demark the edge of the RCLV based on 32-day backward-in-time Lagrangian trajectories. In other words, eddies in this dataset represents a fluid mass of substantial size that was coherent for at least 32 days. The fluid masses are tracked through time to assign IDs and RCLV ages. The software used to generate the dataset is publicly available at https://github.com/lexi-jones/RCLVatlas (DOI: <a href="https://doi.org/10.5281/zenodo.7702978" target="_blank" rel="noopener noreferrer">10.5281/ZENODO.7702978</a>).</p> <p>Version 1 of the dataset (https://simonscmap.com/catalog/datasets/RCLV_atlas; DOI: <a href="https://doi.org/10.5281/zenodo.8139149" target="_blank" rel="noopener noreferrer">10.5281/ZENODO.8139149</a>) only includes contours that represent features of age 32 days or older. Version 2 extends the dataset to include eddy genesis by advecting the particle sets backward-in-time to age 24, 16, and 8 days.</p>
The North Pacific Eukaryotic Gene Catalog: Raw assemblies from Gradients 1, 2 and 3
<p>The North Pacific Eukaryotic Gene Catalog consolidates eukaryotic metatranscriptome data from three latitudinal transects of the North Pacific transition zone and one cruise in the subtropical gyre. Metatranscriptomes were gathered from latitudinally-resolved surface samples, and diel-resolved temporal studies, with samples taken in triplicate or duplicate and collected on 0.2-100 μm, 0.2-3 μm, and 3 μm-100 or 200 μm size fractions. These metatranscriptome data were <em>de novo</em> assembled into 175 independent assemblies, totalling 182 million clustered nucleotide contigs. Assemblies were annotated by taxonomy and function. This catalog provides assembled environmental contigs, their translated peptide sequences, and their taxonomic and functional annotations with the aim of facilitating continued discoveries about the molecular ecology of microbial eukaryotes in the North Pacific.<br><br>A full description of this data is published in Scientific Data, available here: <a href="https://www.nature.com/articles/s41597-024-04005-5" target="_blank" rel="noopener">The North Pacific Eukaryotic Gene Catalog of metatranscriptome assemblies and annotations</a>.

Time series measurements of nitrogen fixation in the subtropical North Pacific (extended through 2019)
<p>Rates of N<sub>2</sub> fixation were measured using the <sup>15</sup>N<sub>2</sub> isotopic tracer technique. Sampling occurred during near-monthly Hawaii Ocean Time-series cruises. Whole seawater samples from six discrete depths (5, 25, 45, 75, 100, and 125 m) were subsampled into acid-washed 4.3 L polycarbonate bottles. The <sup>15</sup>N<sub>2</sub> gas was first dissolved into seawater and 100 mL of the resulting <sup>15</sup>N<sub>2</sub>-enriched water was added to 4.3 L polycarbonate sampling bottles. The resulting atom % enrichment of stocks of <sup>15</sup>N<sub>2</sub>-enriched seawater was measured using a membrane inlet mass spectrometer. Incubation bottles amended with the <sup>15</sup>N<sub>2</sub> tracer were attached to a free-drifting array and incubated at the discrete depths from which samples had been collected. The array was deployed before dawn and samples were incubated at in situ light and temperature for 24 h. After recovery of the array, the entire volume from each bottle was filtered onto a pre-combusted glass microfiber filter (Whatman 25 mm GF/F) and filters were placed onto pre-combusted pieces of foil in Petri dishes and stored frozen at -20°C. Filters were dried for 24 h at 60°C, pelleted, and the total mass of N and its isotopic signature on each filter were analyzed on an elemental analyzer-isotope ratio mass spectrometer (Carlo-Erba EA NC2500 coupled with ThermoFinnigan Delta S). </p>

Data from" Euphotic Zone Metabolism in the North Pacific Subtropical Gyre Based on Oxygen Dynamics"
<p>This data set provides measurements of oxygen to argon molar ratios from discrete samples collected within the mixed layer at the long-term sampling site (Station ALOHA) of the Hawaii Ocean Time-Series program, within the North Pacific Subtropical Gyre, between November 2013 and January 2019 (near-monthly cruises). Samples were measured by membrane inlet mass spectrometry following Ferrón et al. (2015). Version 2 had corrected longitude data (in decimal degrees east). Version 3 includes a new file with estimated rates of net community production, gross oxygen production and community respiration for the mixed layer.</p>
