This data package includes 2 child items with data from Pacific Black Brant (Branta bernicla nigricans) during winter and migration periods. Child Item 1: "Body mass, Morphological Measurements, Flock Counts, and Age-Ratios from Black Brant Overwintering in Three Lagoons Along the Baja California Peninsula, Mexico". The data include: (1) body mass and morphological measurements from sport hunter harvested brant, and (2) census counts of brant in Bahia de San Quintin, (3) counts for flock age ratio determination, and (4) behavior. Child Item 2: "Black Brant (Branta bernicla nigricans) Radio Detection and Migration Timing Alaska to Mexico". Data from brant tagged with VHF radio transmitters in July 1999 on the Yukon...

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7T43R88 This data package provides data from Pacific Black Brant (Branta bernicla nigricans) tagged with VHF radio transmitters in July 1999 on the Yukon Kuskokwim Delta, Alaska and detected in the following two years during their annual migration. Data include: 1) one table with attributes of the tagged brant, 2) one table with estimated dates of migration events, and 3) seven tables of detection data from radio tracking scans at coastal sites between Alaska and Mexico. Version History: First release: April 2023 Revised: February 2024 (ver. 2.0)

This data release contains monthly 270-meter gridded Basin Characterization Model (BCMv8) climate inputs and hydrologic outputs for the Salton Sea Watershed, which crosses the international border into Mexico in the southern part of the basin. Downscaled gridded climate inputs (Daly et al., 2008) for the California portion of the BCM (Flint et al, 2021) include: precipitation (ppt), minimum temperature (tmn), maximum temperature (tmx), and potential evapotranspiration (pet). Historical climate data covering the Mexico portion of the watershed was unavailable. Climate data for the California portion of the watershed was regridded using regression techniques described in Flint & Flint (2012) to extend climate inputs...
