[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.

[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).

[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.

[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.

[HOT LAVA Nitrogen] - Water column nitrate+nitrite d15N and d18O and total dissolved nitrogen d15N measurements from R/V Ka`imikai-O-Kanaloa cruise KOK1806 (HOT LAVA) in July 2018 (Quantifying nitrogen fixation along unique geochemical gradients in the southwest Pacific Ocean)

Summary:
This data set includes water column nitrate+nitrite and total dissolved nitrogen d15N measurements. These measurements were used to address the source of nitrate+nitrite in surface waters observed after the 2018 Kilauea eruption entered the ocean, leading to enhanced surface ocean chlorophyll. The results are consistent with an upwelling source of nitrate+nitrite from ~400 m driven by hot lava entering the ocean, leading to increased buoyancy of waters, driving \roils\ (see F. J. Sansone, and J. A. Resing, 1995, J. Geophys. Res. Oceans). These data are also used as evidence that biological nitrogen fixation did not contribute to the nitrate+nitrite observed in surface waters.

[HOT Primary Production] - Primary productivity measurements for the Hawaii Ocean Time-Series (HOT) program from October 1988 to December 2023 at Station ALOHA ([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:
Primary productivity measurements from the Hawaii Ocean Time-Series (HOT) program from 1988 through 2023. The 14C-radiotracer method was used to measure the assimilation of dissolved inorganic carbon (DIC) by phytoplankton as an estimate of the rate of photosynthetic production of organic matter in the euphotic zone. All incubations from 1990 through mid-2000 were conducted in situ at eight depths (5, 25, 45, 75, 100, 125, 150 and 175m) over one daylight period using a free-drifting array as described by Winn et al. (1991). Beginning October 2000 (HOT-119), samples were collected from only the upper six depths while the lower two depths were modeled based on the monthly climatology. Starting July 1989 (HOT-008), all incubations were conducted in situ on a free floating, surface tethered array. Integrated carbon assimilation rates were calculated using the trapezoid rule with the shallowest value extended to 0 meters and the deepest extrapolated to a value of zero at 200 meters.

[HOT pTMs, 2020-2023] - Water column particulate metals 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 water column particulate metal samples onboard 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 and filtered onto 0.2 micron polyethersulfone (PES) filters (approx. 4L per sample). Approx. 11 depth samples were collected for each cruise within the upper 300 m of the water column.

Filters were subject to a 2-stage digestion: 1) a "Berger" leach consisting of hydoxylamine and acetic acid, to dissolve labile trace metals, and 2) a digestion with nitric acid and hydrofluoric acid to dissolve recalcitrant metals. Dissolved metals for each leach were 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.

[In situ seawater temperature at Heron Island (2015-2020)] - Measurements of seawater temperature, depth, and photosynthetically active radiation (PAR) across seven sites at Heron Island, southern Great Barrier Reef from 2015 to 2020 (Influence of environmental pH variability and thermal sensitivity on the resilience of reef-building corals to acidification stress)

Summary:
Increasing ocean temperatures threaten coral reefs globally, but corals residing in habitats that experience high thermal variability are thought to be better adapted to survive climate-induced heat stress. Here, we used long-term ecological observations and in situ temperature data from Heron Island, southern Great Barrier Reef to investigate how temperature dynamics within various thermally variable vs. thermally stable reef habitats change during a marine heatwave and the resulting consequences for coral community survival. This data set includes the in-field measurements of seawater temperature, depth, and photosynthetically active radiation (PAR) across seven sites at Heron Island, southern Great Barrier Reef.

Summary:
Increasingly frequent marine heatwaves are devastating coral reefs. Corals that survive these extreme events must rapidly recover if they are to withstand subsequent events, and long-term survival in the face of rising ocean temperatures may hinge on recovery capacity and acclimatory gains in heat tolerance over an individual's lifespan. To better understand coral recovery trajectories in the face of successive marine heatwaves, we monitored the responses of bleaching-susceptible and bleaching-resistant individuals of two dominant coral species in Hawaiʻi, Montipora capitata and Porites compressa, over a decade that included three marine heatwaves. This dataset includes the in situ temperature data from Kāne'ohe Bay, O'ahu, Hawai'i from 2013-2023.

Summary:
During July 20-28 2022 and August 10-20 2023 an underwater imager (In Situ Ichthyoplankton Imaging System 3, ISIIS-3) was deployed from the R/V Langseth and R/V Sally Ride, respectively. The ISIIS-3 deployments were carried out from these R/Vs in the northern California Current by a team affiliated with Oregon State University, the University of Oregon, and Portland State University.

The ISIIS-3 was equipped with two line scan cameras for collecting plankton imagery in addition to six  environmental sensors.

This dataset contains the processed and quality controlled merged environmental data from the ISIIS imager on this cruise, consisting of temperature, conductivity, pressure, depth, salinity, fluorescence, oxygen, pH, photosynthetically active radiation, and chlorophyll a. Latitude, longitude, date, time, imager horizontal/vertical speeds, and altitude are also included in the dataset. Data were collected on six cross-shelf transects ranging geographically from the border of California and Oregon to  southern Washington. Two transects, one following the Newport Hydrographic Line and the other near Gray's Harbor, Washington, were 70 nautical miles (~135 km) in length. The four others (near the Columbia River, Cape Meares, Heceta Bank, and the Rogue River) were 40 nautical miles (~73 km). ISIIS was towed continuously in an undulating motion (“tow-yos”) between 0-100m depth, or within 2-5m of the seafloor where the bottom depth was less than 100m. Data were streamed on to the ship in real time using a fiber optic oceanographic cable and written into millisecond time-stamped data files for each sensor. Sensor data files from ISIIS-3, along with latitude and longitude data from ship data streams, were merged using Python scripts into a final dataset based on the millisecond time stamps of the sensors and GPS streams.

Summary:
The goal of this dataset was to survey the reef fish communities at three artificial reefs constructed in Kāneʻohe Bay, Oʻahu, Hawaiʻi from August 2022-December 2023. Fish community surveys were conducted monthly. Surveys were conducted by the same observer each time who would sit ~3m away from the reef to minimize disturbance, and record all fish seen within 1m of the reef for three minutes. After that time, the observer would move to the reef and attempt for another two minutes to record any fish that may not have been initially visible. This was repeated at each of the three artificial reefs.

[Lab experimental time series of T. suecica densities under fluctuating temperatures] - Time series of T. suecica densities under fluctuating temperatures experiment from May 2023 to Aug 2023 (A novel time-structured framework to account for the cryptic effects of temperature fluctuations on population dynamics)

Summary:
This dataset includes the densities (count/mL) of the alga Tetraselmis suecica (LB 2286) cultures grown from a UTEX sample. The counts were obtained using a Beckman Coulter Z2 Particle Counter in the lab over a five-day period under different experimental temperature regimes. The experiment took place between 2023-05-23 and 2023-08-18. The goal of the experiment was to determine how mean temperature and temperature fluctuation frequency affected the growth rate of T. suecica. By comparing the growth rate of T. suecica under constant vs. variable temperatures, one can determine the historical or legacy effects of past temperature variation on subsequent organismal performance. These experiments were conducted by members of the Brian Helmuth Lab at Northeastern University.

[Lagrangian Trace Metal Concentrations] - Surface and profile concentrations of trace metals and radionuclides near Station ALOHA (Center for Microbial Oceanography: Research and Education)

Summary:
Trace element water samples from KM1513 were collected with the MIT Automated Trace Element (ATE) sampler, deployed with a teflon-coated wire from the ship\u2019s deck for surface water samples (collected at roughly 10 m depth), and with the ATEs attached to PVC \u201cVanes\u201d designed to prevent contamination from the ship\u2019s steel wire for samples collected at greater depth. Samples were filtered at 0.4 \u03bcm immediately after collection through polycarbonate track etched filters (Nucleopore) into 250 mL HDPE bottles and acidified to 0.012 M hydrochloric acid (ultrapure by quadruple distillation in a Vycor still; ~pH 2) at sea. Sampling and filtration followed published protocols used previously at Station ALOHA, for direct comparison (Fitzsimmons et al., 2015). These casts mostly aligned with Niskin cast station locations, but in some cases did not.

[Large Volume Pump Data from EN665] - Small and large particle concentrations of total carbon, total nitrogen, and inorganic carbon, and particulate thorium-234 and RAP234 from large volume pump profiles collected on R/V Endeavor cruise EN665 in the Gulf of Maine in April 2021 (Biogenic Calcium Carbonate Solubilities and Reaction Rates by Lab and Field Saturometry)

Summary:
Sample collection took place at two primary stations within the Gulf of Maine's Wilkinson and Jordan basins from the R/V Endeavor in April 2021. McLane pumps were deployed at eight depths throughout the water column from near the sea surface (~14 meters) to near the seafloor (~250 meters). The first deployment occurred in the Wilkinson Basin and the second occurred in the Jordan Basin. Small (1-51 micrometer (µm)) and large particle (>51 µm) concentrations of total carbon, total nitrogen, and inorganic carbon (PC, PN, and PIC, respectively) are presented, along with small particle isotopic compositions (13C, 15N) of these phases, particulate thorium-234, and RAP234 (a resuspension proxy associated with particulate thorium-234). Depth profiles demonstrate typical particulate carbon shapes. The PIC demonstrates a peak near the seafloor, indicating the potential presence of a nepheloid layer. This feature does not appear in the PC data. The isotopic composition of the PIC demonstrates uniquely negative values throughout the water column. Small particle thorium-234 activities were consistently larger than the large particle activities at all depths and small particle RAP234 activities indicate possible resuspension in the bottom ~50 m of the water column. These data were collected by Drs. Adam Subhas (WHOI) and Erin Black (UR). Data processing and preparation were completed by Dr. Subhas, Dr. Black, and Karine Holmes (UR).

[Lobster Larvae Respirometry Data] - Oxygen consumption by lobster larvae at different temperatures using closed cell respirometry for lobster larvae from Gulf of Maine near Boothbay Maine from 2021 to 2023 (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 oxygen consumption and scope for activity (defined as the difference in oxygen consumption between larvae at rest and larvae swimming actively).  This data set includes the raw oxygen consumption data obtained through closed system microrespirometry and subsequently used to calculate scope for activity.  These data were collected between 2021-2023 at Bigelow Laboratory for Ocean Sciences, led by Eric Annis.

[Major inorganic ions in Primary Marine Aerosol (PMA) generated near the BATS station, cruises AE2113 and AE2303] - Major inorganic ions in Primary Marine Aerosols (PMA) generated from seawater collected near the BATS station during R/V Atlantic Explorer cruises AE2113 (July 2021) and AE2303 (January 2023) (Collaborative Research: Seasonal Variability in refractory dissolved organic carbon fluxes associated with primary marine aerosol emitted from the oceans)

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.

[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.
