| Equipment | Usage description | Data types | Datasets |
|---|---|---|---|
| 3.5 kHz | The subbottom data were collected using an Ocean Research Equipment 3.5-kHz subbottom profiler transmitting at a 0.25 second repetition rate. These data were logged in analog form on a paper chart recorder. | Sub Bottom Profiler | 8 |
| Grab sampler | The equipment used was actually an underway pipe sampler described by Brooks and others, 1998 (Brooks, G.R., Doyle, L.J., DeWitt, N.T., and Suthard, B.C., 1998, Inner West-Central Florida continental shelf: Surface sediment characteristics and distribution: U.S. Geological Survey Open-File Report 98-37, 48 p., https://doi.org/10.3133/ofr9837) | Biology, Geology | 5 |
| DGPS | Navigation | 2 | |
| Klein 531 sidescan | 100-kHz Klein sidescan sonar system set to a 100-m range to either side of the trackline. These data were logged digitally on a QMIPS data logger. | Sidescan | 6 |
| Q-MIPS sidescan sonar system | Sidescan | 1 | |
