Science Datasets
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.
Metabolic Rates Measured in Three Captive Adult Female Walruses (Odobenus rosmarus divergens) While Resting and Diving
This dataset contains measurements of oxygen consumption and carbon dioxide production of 3 adult female walruses (Odobenus rosmarus divergens) while resting and diving at the Oceanografic Aquarium in Valencia, Spain. Oxygen consumption and carbon dioxide production was measured for walruses via a respiratory dome while resting at the water surface and after swimming and diving.
Water Level, Temperature, and Discharge in West Twin Creek, Alaska, 2010 to 2012
This data set includes 15-minute interval data on stream temperature, stage, and discharge from an upstream and downstream gaging location on West Twin Creek, a first-order tributary to Nome Creek in the White Mountains of Alaska.
Surrogate regression models for computation of time series suspended-sediment concentrations, Chester County, Pennsylvania (2020)
In cooperation with the Chester County Water Resources Authority (CCWRA), USGS collected discrete stream samples for analysis of suspended-sediment concentrations at seven gaging stations where near real-time continuous data on stream discharge, and turbidity have been collected since 2005. Regression models were developed to estimate suspended sediment from turbidity measurements at each gage...
Idealized COAWST numerical model for testing marsh wave thrust and lateral retreat dynamics routines
There are two idealized domains developed in this work to test the marsh dynamics in the COAWST modeling framework.
1. First idealized domain is to test and verify the lateral thrust calculations.
2. Second idealized domain is to test the implementation of lateral retreat formulations
COAWST model of Barnegat Bay creeks to demonstrate marsh dynamics
The COAWST modeling framework was extended to add two key processes that affect marshes, erosion due to lateral wave thrust (LWT) and vertical accretion due to biomass productivity. The testing of the combined effects of integrating these two processes was done by modeling marsh complexes within Forsythe National Wildlife Refuge and the Barnegat Bay estuary, New Jersey.
Donated ROV vibracore and sampling data collected during Monterey Bay Aquarium Research Institute cruises in 2019 offshore of south-central California
This dataset includes photographs of vibracores that were collected by the Monterey Bay Aquarium Research Institute in February 2019 and November 2019 aboard R/V Western Flyer using the remotely operated vehicle Doc Ricketts. The collection of these cores was funded entirely by MBARI, and the cores have been donated to the USGS. The cores were collected in collaboration with...
Piston and gravity core data collected during USGS cruise 2019-642-FA offshore of south-central California in support of the Bureau of Ocean Energy Management California Deepwater Investigations and Groundtruthing alternative energy project, Sept. 2019
This data release includes photographs, multi-sensor core logger, porewater analyses, and location and depth data from piston and gravity cores collected off the south-central California coast. This dataset is one of several collected as part of the Bureau of Ocean Energy Management-funded California Deepwater Investigations and Groundtruthing project. The purpose of the study is to assess ...
Grain-size data from core S3-15G, Monterey Fan, Central California
This data release presents sediment grain-size data from samples collected from core S3-15G, a 4.72-m long gravity core collected at a depth of 3,491 meters on the western levy of the Monterey Fan on May 31, 1978 (USGS Field Activity S-3-78-SC).
Ephemeral channel heads and digital elevation models used to extract stream networks in Clarksburg, MD (ver. 2.0, October 2021)
This dataset describes the location of channel heads survyed in two headwater watersheds in Clarksburg, Montgomery County, Maryland, and the digital elevation models derived from light detection and ranging (lidar) covering the two watersheds.

Hydrodynamic, sediment transport, and sediment flocculation data from south San Francisco Bay, California, summer 2020
USGS collected hydrodynamic and suspended sediment flocculation data at channel and shallow water sites in south San Francisco Bay in July 2020. The data were used to determine water column stratification, turbulence profiles, and floc size evolution. The goal of this project was to bound the controls on floc size and floc settling velocity to improve estimates of sediment fluxes and consider...
Geophysical properties, geochronologic, and geochemical data of sediment cores collected from San Pablo Bay, California, October 17-20, 2016
P-wave velocity, gamma ray density, and magnetic susceptibility, radiocarbon, excess Lead-210, and Cesium-137, and organic carbon content and 60 element contents are reported for select vibracores collected aboard S/V Retriever October 17-20, 2016 in San Pablo Bay, California. Geophysical properties were measured with a Geotek Multi-Sensor Core Logger. Radiocarbon was measured by...
2020 Hydrologic Data Summary for the Central Pine Barrens Region, Suffolk County, New York
This U.S. Geological Survey data release provides surface-water quality, streamflow, and groundwater-elevation data collected within the Central Pine Barrens (CPB) Region of Suffolk County, New York, from October 1, 2019 through September 30, 2020.
