CoSMoS (Coastal Storm Modeling System) modeled flood hazards for Pierce County, Washington CoSMoS (Coastal Storm Modeling System) modeled flood hazards for Pierce County, Washington
This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR), projected coastal storms, and streamflow. Products include projected flood depths, flood extents including uncertainties, water elevations, velocity hazards, and flood duration. These are generated using a suite of numerical models driven by outputs from Global Climate Models...
Phytoplankton pigment data collected from surface waters in the Lake Pontchartrain estuary, Louisiana, from November 2024 to May 2025 Phytoplankton pigment data collected from surface waters in the Lake Pontchartrain estuary, Louisiana, from November 2024 to May 2025
Monthly surface water samples were collected at sites in the Lake Pontchartrain estuary to assess the phytoplankton biomass and composition using algal pigment analysis. A total of 27 algal pigments including chlorophyll a and accessory pigments were evaluated from each of the water samples.
Hydrology data from selected Louisiana freshwater forested wetlands 2004-2022 Hydrology data from selected Louisiana freshwater forested wetlands 2004-2022
Infinity water level recorders were installed in 2004 to monitor hydrologic conditions in five freshwater forested wetlands in Louisiana: Bayou Chevreuil, Bayou Teche National Wildlife Refuge, Mandalay National Wildlife Refuge, Jean Lafitte National and Historical Park, and Treasure Island. Hourly measurements were collected continuously on a 24- hour basis through April 2022, producing...
Integrated Population Model & Population Viability Analysis of the Cape Sable Seaside Sparrow (CSSS, Ammospiza maritima mirabilis) Integrated Population Model & Population Viability Analysis of the Cape Sable Seaside Sparrow (CSSS, Ammospiza maritima mirabilis)
This software release contains the R code to jointly run an integrated population model (IPM) and Bayesian population viability analysis (BPVA) for the Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis). The CSSS is a federally endangered bird endemic to a small part of the Everglades in southern Florida, USA. The IPM-BPVA synthesizes thirty years (1992-2021) of range-wide...
Immediate impacts of tropical storms on the avian breeding community at Whiskey Island, Louisiana from 2015-2020 Immediate impacts of tropical storms on the avian breeding community at Whiskey Island, Louisiana from 2015-2020
We monitored breeding birds at Whiskey Island, Louisiana between March through July from 2015 to 2020. We surveyed all available habitat by foot, using high-powered spotting scopes and binoculars to search for and identify nesting birds. We documented species, abundance, habitat, location, and breeding behavior for each bird that we observed to be breeding. We modeled the counts of...
