Seafloor Uplift and Deflation (BOTSFLU)

Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e., “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure.

Associated Parameters

  • Seafloor Uplift and Deflation – Mean Seafloor Pressure (BOTSFLU-MEANPRES). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product is 15-second mean seafloor pressure. Units: psi.
  • Seafloor Uplift and Deflation – Mean Seafloor Depth (BOTSFLU-MEANDEPTH). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product is derived by conversion of the 15-second mean seafloor pressure and removal of the tidal signal predicted for the BOTPT instrument location. Units: meters.
  • Seafloor Uplift and Deflation – 5-min Rate of Depth Change (BOTSFLU-5MINRATE). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product is the instantaneous rate of depth change derived from the 15-sec Mean Seafloor Depth Detided using a backward-looking 5 minute reference point for the depth difference. Units: cm m-1
  • Seafloor Uplift and Deflation – 10-min Mean Seafloor Uplift Rate (BOTSFLU-10MINRATE). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product utilizes the 15-second Mean Seafloor Depth Detided and calculates a mean for each data point over a 10 minute backward-looking window. The rate is derived from the backward-looking depth difference between values with a 10 minute offset. Units: cm h-1
  • Seafloor Uplift and Deflation – Daily Mean Seafloor Depth (BOTSFLU-DAYDEPTH). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product is calculated using a 24-hour window centered on 00:00 hours GMT and applied to 15-sec Mean Seafloor Depth Detided data. It is corrected for pressure sensor drift annually- or biennially- using ROV-based field measurements. Units: meters.
  • Seafloor Uplift and Deflation – 4-Week Mean Rate of Seafloor Uplift (BOTSFLU-4WKRATE). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product is the mean rate of seafloor depth change as calculated by 4-week backwards-looking linear regressions. Uplift is positive. Units: cm yr-1.
  • Seafloor Uplift and Deflation – 8-Week Mean Rate of Seafloor Uplift (BOTSFLU-8WKRATE). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product is the mean rate of seafloor depth change as calculated by 8-week backwards-looking linear regressions. Uplift is positive. Units: cm yr-1.
  • Seafloor Uplift and Deflation – Predicted Tide (BOTSFLU-PREDTIDE). Seafloor Uplift and Deflation is a measure of the inflation and deflation (i.e.- “breathing”) of the seafloor. These data are calculated using Nano-resolution Bottom Pressure. This data product is the tide calculated at 15-second time intervals for the location of each BOTPT instrument using tide-prediction software. Units: meters.
