Data and Tools

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.

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...

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...
