Abstract

This GeoTiff is a representation of seafloor topography in Northeast Puerto Rico derived from a bathymetry model with a principle component analysis (PCA). The area covered includes the shallow water area (0-60m deep) of the Northeast Ecological Reserves: including the waters off of Fajardo and Luqillo, to the Former Roosevelt Roads Navy Base, the Vieques Sound, La Cordillera Reserve, the Luis Pena Reserve, and the waters around Culebra Island. The PCA image was created using Envi 5.1, and is based on nine morphometric derivatives of the bathymetry, such as slope, curvature and rugosity. The bathymetry model was created by integrating soundings from several different sources (1900-2013), including high resolution coastal LiDAR, NOAA Single-beam and multibeam bathymetry, and historical lead line soundings, into a multi resolution (4m, 20m, 100m) depth model. The PCA image was used to delineate the different shallow water benthic habitats of NEPR.

Abstract:

This GeoTiff is a representation of seafloor topography in Northeast Puerto Rico derived from a bathymetry model with a principle component analysis (PCA). The area covered includes the shallow water area (0-60m deep) of the Northeast Ecological Reserves: including the waters off of Fajardo and Luqillo, to the Former Roosevelt Roads Navy Base, the Vieques Sound, La Cordillera Reserve, the Luis Pena Reserve, and the waters around Culebra Island. The PCA image was created using Envi 5.1, and is based on nine morphometric derivatives of the bathymetry, such as slope, curvature and rugosity. The bathymetry model was created by integrating soundings from several different sources (1900-2013), including high resolution coastal LiDAR, NOAA Single-beam and multibeam bathymetry, and historical lead line soundings, into a multi resolution (4m, 20m, 100m) depth model. The PCA image was used to delineate the different shallow water benthic habitats of NEPR.

Purpose:

The PCA, multibeam bathymetry, WorldView-2 Satellite imagery and ground validation imagery were used to create benthic habitat maps, helping NOAA meet its mapping commitment to the US Coral Reef Task Force. The resulting publicly-distributed data is also a contribution to the greater scientific community interested in the Caribbean seafloor. The spatial products developed from this bathymetry model will: (1) inform local managers as to the current distribution of resources, (2) provide a point of comparison for past and future mapping efforts, (3) help locate sensitive marine communities, and (4) guide monitoring efforts and prioritize management actions.

Process Steps

Process Step 1

CC ID: 599466
Description:

Bathymetry datasets within the Northeast Reserve area of interest were acquired through the NGDC data viewer and were vertically referenced to the NOAA MLLW tidal datum. The Bathymetry datasets were used to create three bathymetry models (resolution 4m, 20m, and 100m) using kriging in Surfer. The three layers were stacked with the highest resolution on top and merged to one multiresolution surface. Simple kriging in ArcGIS was used to minimize the edge interpolation effects between the three models. The stacked multiresolution bathymetry model and uncertainty surface was up-sampled to 4m resolution using a spline function to create the final bathymetry model. | Source Produced: NEPR Bathymetry Model - 4m

Process Date/Time: 2013-10-01 00:00:00
Source: NEPR Bathymetry Model - 4m

Process Step 2

CC ID: 599467
Description:

The NEPR Bathymetry model was processed using the ArcGIS Spatial Analyst Toolbox into derivative morphometric layers: slope, slope of slope, rugosity, curvature, curvature profile, curvature plan, standard deviation, and mean bathymetry. The morphometric layers were then stacked into a 9 layer raster dataset in Envi 5.1, which was then used for the principle component analysis. | Source Produced: NEPR Morphometric Layers - 4m

Process Date/Time: 2013-10-01 00:00:00
Source: NEPR Bathymetry Model - 4m

Process Step 3

CC ID: 599468
Description:

The stacked morphometric layers were then statistically analyzed by the eigenvalues for covariance in Envi 5.1. This combines all of the layers and shows the variations and complexity of the seafloor terrain, which highlights the different habitats. The result was a 3-band geotiff image. The PCA image was then used to delineate features and help create the benthic habitat map. | Source Produced: NEPR Principle Component Analysis - 4m
