Samples of sediment that have been collected by vibracoring, grab sampling or jet probing. Data associated with individual samples, cores and core layers is accessible through the Query and Identify functions of the ROSSI Map Viewer. Data associated with cores or samples can be accessed in the map by clicking on a core or sample feature in the map, then clicking the More Info link to open the core or sample details page.
Sediment samples that have been collected by vibracoring only. This layer contains information related to core locations and core lengths, along with any associated docuements such as core logs, photos, sediment statistics sheets and granularmetric curves. If samples have been taken from the vibracores, the data associated with the samples (i.e. Munsell color, gradation analyses, carbonate content, etc) may be accessed through the More Info page.
Sediment samples collected by using a long pipe into which water under high pressure is pumped in order to penetrate into unconsolidated sediment. This layer contains information related to jet probe location, core lengths and core layer descriptions. Where samples have been analyzed for grain size etc, the analysis data may be accessed through the More Info page.
Sediment samples collected using a grab technique. They are small samples taken at random or pre-selected frequencies. These samples only define the characteristics of an area at the specific time that they were collected. This layer provides location information, along with full details accessed on the More Info page.
This layer contains Project Level data associated with all sediment samples, regardless of collection method (i.e. vibracore, jet probe, grab sample).

Identification of portions of the seismic tracklines to be used as reference when downloading data from the site. Click on a point to view the data associated with that point. The ID can be used to reference particular portions of the images that can bbe downloaded from the links in the Geophysical Track Lines layer.
Record of the time (typically on a regular interval) at which the geophysical record was collected. This number serves as a reference mark when reviewing and interpreting seismic images. This number can also be used as a reference mark when viewing two adjacent images along the same geophysical track line.

Segments of the shoreline where natural processes or human activity have caused or contributed to erosion and recession of the beach or dune system to such a degree that upland development, recreational interests, wildlife habitat or important cultural resources are threatened or lost. This layer provides an inventory of Florida’s coastal erosion problem areas and contains information related to the location (county, R monument etc) of both critically and noncritically eroded areas and their extent. Information is based on the 2000, 2002 and 2005 critical erosion reports.
