Great Bay, NH - BBL Data June 2011 dataset information page

Short Description

Average velocity profile of tidal bottom boundary
layer over lowest 2.5 cm of the water column.
Dashed lines are regression lines.

Statement: Fine resolution bottom boundary layer velocity measurements in a tidal estuary

Abstract: This data set provides acoustic measurements of the bottom boundary layer in a tidal current over flat muddy-sand bed. Observations made with Nortek Vectrino Profiler over the lowest 2.5 cm of the water column with a 1 mm resolution. Observations were made in June of 2011 just after slack tide during a flood tidal flow. Please contact Diane Foster of the University of New Hampshire with any questions (
