Quantifying ecosystem responses to extreme events at the landscape scale is critical for understanding and responding to climate-driven change but is constrained by limited data availability. Here, we integrated remote sensing with ground-based observations to quantify landscape-scale vegetation damage from an extreme climatic event. We used ground- and satellite-based black mangrove (Avicennia germinans) leaf damage data from the northern Gulf of Mexico (USA and Mexico) to examine the effects of an extreme freeze in a region where black mangroves are expanding their range. The February 2021 event produced coastal temperatures as low as -10 \u2103 in some areas, exceeding thresholds for A. germinans damage and mortality. We used Sentinel-2 surface reflectance data to assess vegetation greenness before and after the freeze, along with ground-based observations of A. germinans leaf damage.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9C4E2CW", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.6466a744d34ec11ae4a7d9ff.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6466a744d34ec11ae4a7d9ff", "keyword": ["Avicennia germinans", "Florida", "Gulf of Mexico", "Louisiana", "Sentinel-2", "Texas", "USGS:6466a744d34ec11ae4a7d9ff", "biota", "ecological threshold", "extreme freeze", "mangroves", "range limit", "remote sensing"], "modified": "2023-08-15T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-97.6245, 27.3718, -82.3535, 30.3160", "theme": ["geospatial"], "title": "Mangrove damage along northern Gulf of Mexico from extreme freeze event on February 2021"}
