Florida Bay Bottom Types map

Entry ID: USGS_SOFIF_Fbbtypes

Summary

Abstract: The map shows the bottom types for Florida Bay that resulted from site surveys and boat transects (summer 1996-January 1997) compared with aerial photographs (December 1994-January 1995) and SPOT satellite imagery (1987).

The purpose of this map is to describe the bottom types found within Florida Bay for use in 1) assessing bottom friction associated with sediment and benthic communities and 2) ...

Quality Over 650 sites in the Bay were located and examined using a small, flat-bottomed boat, high resolution GPS and snorkeling gear.

Local information was recorded in the Bay using a military style GPS unit - Rockwell Precision Lightweight GPS Receiver PLGR+96 with a precision of +/- 10m.

During the summer of 1996 through January 1997 site surveys were ... conducted in Florida Bay. A small, flat-bottomed boat, high resolution GPS, and snorkeling gear were used to locate and examine over 650 sites within the Bay. In areas where depth and water clarity permitted, observations from the boat along transects between survey sites were used to identify the extent of bottom types. Over 100 sediment samples were collected and analyzed for grain size, mud, water, carbonate and organic content. Two descriptors were considered particularly important - the density of the seagrass and sediment texture.

The site surveys and boat transects were compared with aerial photographs from December 1994 - January 1995 and SPOT satellite imagery from 1987 to produce the map of bottom types for Florida Bay. The map of bottom types was created using CPS3 (Contour Plotting System software) and ArcInfo 7.0.3.

The original of this map has been lost. The following information pertains to the recreated map on the SOFIA web site.

The data were reprojected from UTM ZONE 17, NAD83 to GEOGRAPHIC, NAD83 for SUDS 5/20/02.

The map was created using CPS3 (Contour Plotting System software), ArcInfo7, and AMLs. The coverage was converted to a shapefile to be used on ArcView applications.

Descriptions: The description of the sediment data and use of ArcView assumes the reader has limited knowledge of ArcView 3.2.

sed.apr is a project file that might come in handy to quickly look at the data. Edit the .apr file and search for the pathnames for newsed4 and sedpts97. Change the file names to where the data files are stored.

The sed.avl file contains the shade set for the sed data. In ArcView, add the newsed4 theme, and then bring up the legend editor, legend type-unique value, values field - sedname. Then 'load' the sed.avl, and it will look like the map that Ellen Prager produced.

There is also a layout of the map that looks like what she published (although this layout was recreated for the web site). The newsed.ps postscript file is 8.5 X 11 inches. Or desired portions can be printed from the layout.

Problems bringing this in to Adobe Illustrator to print it were corrected by just changing the mudbank color (removing the stippling) in ArcView.

Access Constraints None

Use Constraints None. However, the resolution of the map has been selected to define broad regions for use in modeling efforts.
