Abstract:

Land subsidence rates across Tutuila and Aunuu are drawn from recent work by Huang et al. (2022) showing that the average rate of subsidence on these islands is spatially variable and ranges from 6 to 9 mm/yr. The study analyzed all available radar data from the European Space Agency (ESA) Sentinel-1 satellite, which covers Tutuila and Aunuu only, and derived an average subsidence rate for the 6-year period between September 2015 to December 2022. Data are available over areas where radar data was successfully used to retrieve unambiguous measurements. Vertical land motion (VLM) measurements are provided by this data layer in millimeters per year (mm/yr), with negative values indicating land subsidence.

Purpose:

PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region.

Credit:

The Pacific Islands Ocean Observing System (PacIOOS) is funded through the National Oceanic and Atmospheric Administration (NOAA) as a Regional Association within the U.S. Integrated Ocean Observing System (IOOS). PacIOOS is coordinated by the University of Hawaii School of Ocean and Earth Science and Technology (SOEST).

Protocol: OGC:WMS-C
Description: Open Geospatial Consortium Web Map Service - Cached (WMS-C). Use of WMS-C is similar to traditional WMS but with the addition of the "tiled=true" parameter, which triggers GeoServer to pull map tiles from GeoWebCache if they have been previously generated. This can dramatically improve performance, especially for larger datasets. Supported map formats include JPEG and PNG. Supported info formats include GeoJSON, GML, HTML, and plain text.
