Description:

Abstract:

Provided here are raster geospatial data from five bays along the west coast of the Baja California Peninsula, Mexico (Bahia San Quintin, Laguna Ojo de Liebre, Estero Coyote, Laguna San Ignacio, and Estero San Juanito). The raster data in two folders: 1) "habitat_classifiedRaster_baja_ward": GeoTIFF files characterizing the habitat distribution of seagrass beds, salt marshes, and mangroves, derived from satellite imagery and aerial photomosaics, and 2) "aerialPhotomosaic_baja_ward": the orthorectified aerial photomosiacs used in analysis. At Laguna San Ignacio, Estero Coyote, and Estero San Juanito habitat classification was derived from aerial photos acquired in January 2000. At Laguna Ojo de Liebre habitat classification was derived from Landsat-5 imagery acquired in 1999. At Bahia San Quinitin habitat classification was derived from Spot-1 satellite imagery acquired in 1987 and Landsat-5 imagery acquired in 2000, 2011, and 2014.

Purpose:

Coastal waters along the Baja California Peninsula contain extensive beds of seagrass (eelgrass: Zostera marina and widgeongrass: Ruppia marina), but the status and trends of distribution are unknown. This dataset provides baseline information on the spatial extent and distribution of seagrass, salt marshes, and mangroves in Bahia San Quintin, Laguna Ojo de Liebre, Estero Coyote, Laguna San Ignacio, and Estero San Juanito, enabling a monitoring program for these coastal habitats that support many species including waterfowl.

Supplemental_Information:

The creation of this dataset was a collaborative effort between the U.S. Geological Survey, Ducks Unlimited de Mexico, and the U.S Fish and Wildlife Service.

Methodology:

Methodology_Type: Field
Methodology_Description:

Ground-truth data were collected during field surveys and are reported in a separate U.S. Geological Survey data releases (Ward 2022). Ground-truth data were collected at numerous points in bays over 9 to 19-day periods in late fall and early winter of 1998, 1999, 2005, and 2012 at 5 sites: Bahia San Quintin, Laguna Ojo de Liebre, Laguna San Ignacio, Estero Coyote, and Estero San Juanito.

In short, survey points were distributed across each of these embayments using a systematic design and accessed points by boat using a global positioning system (GPS) unit. Points were sampled by snorkeling in dry suits during high tide. At each point, substrate type and depth and percent cover of eelgrass and seaweeds were estimated within four 0.25 square meters quadrats.

We used the survey points to guide selection of training polygons for each classification category (Ozesmi and Bauer, 2002). This approach enabled the selection of training data across thousands of pixels in each of the images, greatly improving the accuracy of the classifications.

These data were derived from satellite imagery and aerial photographic images

Source_Used_Citation_Abbreviation: EROS_Landsat
Source_Used_Citation_Abbreviation: Spot 1
Process_Date: Unknown

Process_Step:

Process_Description:

Image data were calibrated to at-sensor radiance, corrected for atmospheric path interference, and checked for georeferencing accuracy. The images were corrected for atmospheric interference using dark pixel subtraction.

Source_Used_Citation_Abbreviation: EROS_Landsat
Source_Used_Citation_Abbreviation: Spot 1
Process_Date: Unknown

Process_Step:

Process_Description:

The imagery was classified into land cover categories. The classification was conducted using a combined Isodata (Unsupervised) / Maximum Likelihood (Supervised) methodology. The Isodata classification was used to identify 35 statistically distinct spectral classes which were then assigned to training classes for subsequent Maximum Likelihood analysis. Details of image acquisition, processing, and interpretation are provided in Hogrefe et al 2014.
