Data Releases

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.

Fine-scale behavior of sea turtles in the Gulf derived from acceleration data loggers, 2018 - 2023 Fine-scale behavior of sea turtles in the Gulf derived from acceleration data loggers, 2018 - 2023

This release contains data from acceleration data logger (ADL) float packages designed to 'pop-off' in a set amount of time for recovery and platform terminal transmitter (PTT) satellite tags attached to 12 Kemp's ridley (Lepidochelys kempii) and 7 Loggerhead (Caretta caretta) turtles in several geographic locations, using the methods of Hart et al., 2013. These instrument packages...

Modelled long-term wildfire occurrence probabilities in sagebrush-dominated ecosystems in the western US (1985 to 2019) Modelled long-term wildfire occurrence probabilities in sagebrush-dominated ecosystems in the western US (1985 to 2019)

Exotic annual grasses are one of the most damaging biological stressors in western North America and increase the susceptibility of landscapes to wildfire occurrence. Here we couple estimates of long-term rangeland component fractions (e.g. exotic annual grasses) with remote sensing, climate data, and machine learning techniques to estimate the long-term (1985 to 2019) probability of...

Historic and future trends in exotic annual grass (%) cover in the western US (1985 to 2019 and 2025 to 2040) Historic and future trends in exotic annual grass (%) cover in the western US (1985 to 2019 and 2025 to 2040)

Exotic annual grasses [EAG] are one of the most damaging biological stressors in western North America. Despite numerous environmental and societal impacts associated with EAG there remains a need to enhance regional monitoring capabilities to better guide management and conservation efforts. Here we provide estimates of historic and potential future trends in EAG abundance that were...

Probabilistic estimates of landscape change in Alaska (1984 to 2015) Probabilistic estimates of landscape change in Alaska (1984 to 2015)

Contemporary climate change in Alaska has resulted in amplified rates of press and pulse disturbances that drive ecosystem change with significant consequences for socio-environmental systems. Despite the vulnerability of Arctic and boreal landscapes to change, little has been done to characterize landscape change and associated drivers across northern high-latitude ecosystems. Here we

CoSMoS-AK Modeled flood and erosion hazards at Unalakleet - Coastal Alaska CoSMoS-AK Modeled flood and erosion hazards at Unalakleet - Coastal Alaska

This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR) and projected coastal storms. Products include projected flood depths, flood extents including uncertainties, water elevations, wave heights, velocity hazard, and erosion and sedimentation pattern. These are generated using a suite of numerical models driven by outputs from...
