This dataset contains short-lived radioisotope (SLRad), sediment core photographs, and bulk density/porewater data from sediment cores collected aboard R/V Weatherbird II cruises WB-0813 and WB-1405 in the Gulf of Mexico from 2013-08-15 to 2013-09-27. Bulk density/porewater data reports measurements of sediment sample wet weight (g) and dry weight (g) for core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to the base of cores. SLRad data were generated for selected core sub-samples.

This dataset includes surface underway, chemical, meteorological and physical data collected during the CCGS Amundsen 2016 Green Edge cruise AN1601 (ArcticNet Leg 1, EXPOCODE 18DL20160603) in Baffin Bay from 2016-06-03 to 2016-07-10. These data include partial pressure of CO2 (pCO2), fugacity of CO2 (fCO2), mol fraction of CO2 (xCO2), sea surface salinity and sea surface temperature.

This dataset includes surface underway, chemical, meteorological and physical data collected from R/V F.G. Walton Smith in the Gulf of Mexico and North Atlantic Ocean in 2021. These data include air-sea difference of partial pressure of carbon dioxide (pCO2), pCO2 in atmosphere, pCO2 in water, barometric pressure, sea surface salinity and temperature. The instruments used to collect these data include barometric pressure sensor, carbon dioxide gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide measurement and thermosalinographs.

This dataset contains water temperature, salinity, and oxygen profiles taken by CTD and water sampling. Cruise RB-20-06 by NOAA Ship Ronald H. Brown in 2020 had the objective to service moored platforms for the NTAS and MOVE projects (Northwest Tropical Atlantic Station and Meridional Overturning Variability Experiment). To calibrate and validate the mooring data, CTD casts with salinity water samples were collected; these data are reported here. The CTD sensor data have been quality-controlled and adjusted using the water sample data. The raw CTD data are available as separate files.

This dataset contains oceanographic data (ADCP, CTD, underway), submersible data, images, and documentation. The cruise focused on several seep sites, canyons, and hard bottom features located less than 100 nm offshore. The goal of this expedition was to validate several seep targets, image and map seeps, canyons (e.g., Keller, Pamlico, Hatteras, and unnamed canyons), and hard bottom features located between Virginia and Georgia.

This dataset contains historical temperature, salinity, and dissolved oxygen data taken by CTD off Peru by Instituto del Mar del Perú (IMARPE). Data are in CSV format. Summary of measurement coordinates is in text format.

This dataset consists of surface measurements of partial pressure of CO2 (pCO2), pH on total scale, water temperature, salinity, and other variables in the Casco Bay, Gulf of Maine from 2015-04-23 to 2020-06-12. The central goal of this project was to install continuous monitoring sensors in Casco Bay to measure ocean and coastal acidification parameters at high temporal resolution. The system was installed at the Southern Maine Community College (SMCC) pier in South Portland, Maine.

This dataset contains water temperature, salinity - surface water, microbial abundance, and others taken by CTD and water samples. As a part of the Malaspina circumnavigation cruise, the BIO Hesperides crossed US waters around Hawaii. CTD casts were used to obtain water for measurements of microbial abundance and nutrients and chlorophyll data. Data for three stations around Hawaii (one unclear whether is at the border of the territorial waters). This dataset is U.S. State Department MSR U2011-009 as part of the World Data Service for Oceanography. Data are in XLS and TEXT formats.

This pilot study follows the movements of 6 derelict fishing nets over time to study how far derelict nets can travel within an atoll, and how long they remain stationary. Six floating derelict fishing nets were located and tagged with satellite buoys in Pearl and Hermes Atoll in the Northwestern Hawaiian Islands during a marine debris removal mission in 2018. Locations of the 6 nets were transmitted every four hours from 09-30-2018 until the buoys broke free or stopped transmitting due to technical reasons.

The Southeast Florida Diving and Snorkeling Reef Expenditures Data (“FloridaSnorkelDiveExpenditures_Data2016-17.csv”) consists of expenditure data collected via an online survey during October 2016 to October 2017 in Southeast Florida. The sampling strategy used in this data collection was a two-pronged approach and included a random sample drawn from all registered boaters in Broward, Martin, Miami-Dade, Monroe, and Palm Beach Counties, and an opportunistic sample that was obtained through collaboration with multiple partners and stakeholder entities.
