Time series data of wave height and water surface elevation were acquired at ten locations for 75 days south of Lahaina, off of the west coast of the island of Maui, Hawaii, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs. The relative placement of sensors on the reefs were as follows: MAU17TP1 and MAU17LA1 – middle fore reef MAU17TP2 and MAU17LA2 – upper fore reef MAU17TP3 and MAU17LA3 – outer reef flat MAU17TP4 and MAU17LA4 – middle reef flat MAU17TP5 and MAU17LA5 – inner reef flat

Time series data of water surface elevation, wave height, and water column currents and temperature were acquired at seven locations for 86 days off of Waiakane on the south coast of the island of Molokai, Hawaii, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs. The relative placement of sensors on the reef were as follows: MKK18C01 – offshore MKK18C02 and MKK18C09 – fore reef MKK18C18 – reef crest MKK18C20 – outer reef flat MKK18C22 – middle reef flat MKK18C22 – inner reef flat

The Data Layers include the following.Flooding: Regions that flood during heavy rainfall.Intermittent Streams: Areas flow as streams during heavy rainfall.Community drinking Water Sources: Locations where villagers used to collect water for drinking, most do not use anymore and only use ASPA water.Trash Accumulation: Locations where trash accumulates in streams and other accumulated locations within the village such as corners of roads where water pools.Cultivated Lands: Areas used for cultivation mostly small local cultivations behind households only a few larger cultivated areas.Cesspools: Areas that are not on sewer and still have cesspools. Other Pollution Sources: This category is for other land sources of pollution. Village Clean Up: These areas are designated as village cleanup areas and have a regular schedule for cleanup. Also included in this layer or in a separate layer is information on Government cleanup which happens primarily along the main road.Informal Dump Sites: These data layers indicate where people dump trash within the village, sometimes it is overflow from dumpsters while other points reperesent where trash is commonly dumped.Important Fishing Areas: Indicate regions of important fishing as outlined by the villagers.

Relative turbidity, bathymetry, and environmental correlates (modeled wave height) for insular shelf of American Samoa- from 2002 to 2017 - Ofu, Olosega, and Ta'u region of interest (ONSP6). Data are in gridded netCDF binary format - Hierarchical Data Format (version 5), "NETCDF4 CLASSIC_MODEL".

In 2004, the Environmental Protection Agency (EPA) Environmental Monitoring and Assessment Program (EMAP) National Coastal Assessment (NCA), coordinated through the Gulf Ecology Division, conducted a comprehensive survey of the condition of estuarine resources in American Samoa. The survey sampled 49 stations on islands of Tutuila, Aunu'u Ofu, Olosega, Ta'u during April and August, 2004. The WATER QUALITY MEASUREMENTS data set contains two types of data: hydrologic profile water quality information resulting from in-field observations of physical data and water quality information resulting from laboratory examination of water quality samples for nutrient analyses. The SEDIMENT CHEMISTRY data set contains sediment contaminant information resulting from laboratory examination of samples collected at sites. Each record reports the contaminant name and its associated measured concentration, date site was visited, and the group that collected the data. Only one grab per site was required by the program. The SEDIMENT GRAIN data set contains sediment grain analyses information resulting from laboratory examination of samples collected at sites visited during probability surveys. Each record reports the sediment component and its associated measured concentration, date site was visited, and the group that collected the data. Only one grab per site was required by the program.

Time-series data of water surface elevation, wave height, and water column currents, temperature, and salinity were acquired for 150 days between 13 April and 14 July 2015 off the north coast of the island of Tutuila, American Samoa in support of a study on the coastal circulation patterns within and in the vicinity of the National Park of American Samoa.

This data was collected by Woolpert using a Leica HawkEye 4X sensor. The data was acquired from 20221022 - 20221202. The data includes topobathy data in LAS 1.4 format classified as unclassified (1), ground (2), low noise (7), topo water surface (9), high noise (18), bathymetric point (40), bathymetric water surface (41), synthetic derived water surface (42), submerged object (43), International Hydrographic Organization (IHO) S-57 object (44), submerged aquatic vegetation (64), and bathymetric bottom temporal changes (65) in accordance with project specifications. The lidar data in ellipsoid heights was used to create the final topobathymetric DEMs in ellipsoid heights. Lidar data classes 2, 40 and 43 were used to generate a raster in geotiff format, with 1 meter pixel resolution for the entire area. The raster was then clipped to the tile grid and named according to project specifications to result in tiled 5000m x 5000m topobathymetric DEMs. The project consists of approximately 53 square kilometers of data collected in Ofu-Olesega, American Samoa. This dataset contains 6 5000 m x 5000 m raster tiles.

Time series data of water surface elevation and wave height were acquired at ten locations for 153 days off San Juan, on the north coast of Puerto Rico, in support of a study on the transformation of surface waves and resulting water levels over the coral reefs. The relative placement of sensors on the reefs were as follows: PRI18E01, PRI18W01 – fore reef PRI18E02, PRI18W02 – reef crest PRI18E03, PRI18W03 – outer reef flat PRI18E04, PRI18W04 – middle reef flat PRI18E05, PRI18W05 – inner reef flat PRI18E06 – lagoon PRI18E07 – near-shore

Abstract Reson 8101ER multibeam Data were collected from 30 January and March 12, 2004, aboard NOAA Survey Launch Acoustic Habitat Investigator (AHI) at Tutuila, Ofu, Olosega, and Ta'u Islands in the Territory of American Samoa during cruise AHI0402. The data were logged into datasets titled Manua and Tutuila. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Sound velocity corrections from a Seabird SBE19 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time. Horizontal accuracy is 20m (no differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from 10 - 300 m. The AHI was deployed from the NOAA Ship Oscar E. Sette and surveyed independently during ship operations in other locations in American Samoa. The multibeam bathymetric data in generic sensor format from AHI0402 were submitted to NOAA's National Geophysical Data Center (NGDC) in Boulder, CO, for distribution in 2005.
