Vegetation survey of southwest Florida for use in assessment of the Picayune Strand Restoration Project effects

This release consists of vegetation data collected across an environmental gradient at Ten Thousand Islands National Wildlife Refuge (TTI NWR) near Naples, Florida, USA. The refuge is within the impact area of the Picayune Strand Restoration Project (PSRP), a large-scale hydrologic restoration project in southwest Florida that was authorized by the U.S. Congress in 2007. Vegetation transects were located in the following wetland types on the refuge: brackish marsh, salt marsh, and transition marsh. Data from vegetation transects established in nearby areas outside of the PSRP impact area, in Fakahatchee Strand Preserve State Park (FSPSP) and Big Cypress National Preserve (BICY), are also included. The study spanned...

Fish distribution and tidal currents in the Upper San Francisco Estuary, 2022-2023 (ver. 2.0, March 2024)

This data release includes field data for fishes sampled through mid-water trawls and otter trawl methods from Suisun Bay, California to the mouth of the Sacramento River. These data were collected from the months of September through October in 2022 and 2023 as a part of a multi-year study of Suisun Dredging and Fish Distribution (SDFD). This data release includes quantitative data on collected fish taxa focused on habitat differences between shipping channels and shoals. Sampling was done using short duration (~15 minute) trawls alongside associated water quality sample and Acoustic Doppler Current Profiler (ADCP) data collected at variable locations, depths, times, and currents. First release: May 26,2023 Revised:...

12-Digit Hydrologic Unit Outlet Locations for Selected Watersheds Draining to the Gulf of Mexico in the South-Central and Southeastern United States, Derived from the USGS Watershed Boundary Dataset (dated August 13, 2020) and NHDPlus version 2.1

This USGS data release includes a shapefile of outlet point locations for 12-digit hydrologic units (HU12s) from the Watershed Boundary Dataset (WBD), dated August 13, 2020 (U.S. Geological Survey and others, 2020), draining to the Gulf of Mexico in the south-central and southeastern United States. The outlet locations were derived by combining the WBD boundaries with flow direction grids from the National Hydrography Dataset Plus (NHDPlus) v 2.1 (U.S. Environmental Protection Agency and U.S. Geological Survey, 2012). Most of the outlet locations were determined by finding the cell with highest flow accumulation from the NHDPlus flow-direction grids within each WBD HU12 boundary. Some locations were found to be...

Phytoplankton Community Composition and Abundance in Lake Okeechobee and the Okeechobee Waterway, Florida, USA, July and August 2019

This data release contains phytoplankton classification and enumeration results from two moving boat surveys conducted on July 15 - 18, 2019 and August 19 - 22, 2019. These data were collected from the Caloosahatchee River and estuary, the St. Lucie River and estuary, and Lake Okeechobee with funding provided by the USGS Priority Ecosystems Greater Everglades Program.
