This data set comprises maps of predicted long-term groundfish biodiversity hotspot probabilities off the Pacific Coast of Oregon. Predicted hotspot probabilities are given for four biodiversity indices: 1) relative abundance, 2) relative biomass, and 3) species number for all groundfishes, and 4) relative abundance for only nearshore groundfishes. The nearshore species assemblage includes: Sand Sole, English Sole, Pacific Sanddab, Speckled Sanddab, Petrale Sole, Starry Flounder, and Butter Sole.

Seaglider is a buoyancy driven autonomous underwater vehicle (AUV) developed by scientists and engineers at the University of Washington's School of Oceanography and Applied Physics Laboratory. Seagliders are designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a sawtooth trajectory through the water. Seaglider has entered wide use in scientific deployments. They are designed for missions in range of several thousand kilometers and durations of many months.

This dataset contains oceanographic data collected in the deep water areas around Wake Island and along transits from Guam to Kwajalein. Operations will use the ship’s deep water mapping systems, NOAA’s two-body 6000 m remotely operated vehicles, CTD rosette, and the ship’s high-bandwidth satellite connection for real-time ship to shore communications. Daytime ROV dives were planned most days, as were a few dedicated mapping transit days. ROV dives included high-resolution visual surveys and limited rock and biologic specimen sampling.

This dataset includes water temperature time series, transmissivity, suspended solids, and currents measurements collected from the Elis Olsson in the York River for the Coastal Hydrodynamics & Sediments Dynamics Program (CHSD) from 2007-01-26 to 2011-09-01. These measurements were collected using CTD, Acoustic Doppler Current Profiler (ADCP), Laser In-Situ Scattering and Transmissometer (LISST), and Acoustic Doppler Velocimeter (ADV).

This dataset contains 43 CTD casts made from the RV Walton Smith in the northern Gulf of Mexico near DeSoto Canyon in July-August 2012 as part of the Grand Lagrangian Deployment (GLAD) experiment. These CTD casts were made to determine the hydrography of the upper water column as one way to characterize the meso- and submesoscale variability in the region where 297 CODE-type ocean drifters were launched in an attempt to measure multi-scale near surface dispersion. The drifters were drogued at 1 meter and most of them were launched in triplets (initially separated by roughly 100 meters).

Multiple experiments were conducted to determine the effects hydrogen sulfide had on seedlings and seed germination in the seagrass Zostera marina. One study identified lethal limits of H2S for Z. marina seedlings, as well as identified ranges in which Z. marina seedlings are unaffected by sulfide levels. It was determined that Z. marina seedlings’ growth rates are stunted by H2S levels. Another study identified if anoxia, salinity, sulfide, time the seeds were picked or location the seeds were picked from affected seed germination rates or acted as germination cues.

This dataset reports conductivity, temperature and depth data collected in the Northern Gulf of Mexico during the R/V Weatherbird II cruise WB-1318 from June 24-30th 2013. This data was collected using a CTD sled. Peripheral sensors collected oxygen, fluorescence, turbidity, and photosynthetically active radiation (PAR) data.

59 CTD casts made from small boats launched by the RV Walton Smith in the northern Gulf of Mexico near DeSoto Canyon in July 2012 as part of the Grand Lagrangian Deployment (GLAD) experiment. This dataset was created by the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE). This research was made possible by a grant from BP/The Gulf of Mexico Research Initiative.

Hypoxia has the potential to be a stressor to eelgrass as it can lead to tissue anoxia at night. These tissues then must undergo anaerobic metabolism, which is less energetically efficient and can produce toxic byproducts. Hypoxia may also work in synergy with other stressors, such as sediment pore-water sulfide. Hypoxia can facilitate the intrusion of sulfide, a known phytotoxin, into eelgrass tissues. This study examined the interaction between sulfide and hypoxia on the growth and photosynthetic efficiency of Zostera marina.

Acoustic roundtrip travel time, pressure, ocean velocity, and temperature recorded by Current- and Pressure-recording Inverted Echo Sounders (CPIES) instruments at five mooring locations as part of the Agulhas Current Time-series experiment (ACT).
