The feasibility of sodar wind profile measurements from an oceanographic buoy
(Massachusetts Institute of Technology, 2006)
This thesis explores the feasibility of making wind speed profile measurements from an oceanographic buoy using a Doppler sodar. In the fall of 2005, we deployed a Scintec SFAS sodar on an ASIS buoy. Roughly one week of ...
Seafloor ripples created by waves from hurricane Ivan on the west Florida shelf
(Massachusetts Institute of Technology, 2006)
Recent studies have shown that the presence of sand ripples on the seabed improves sonar detection of buried mines at sub-critical angles. Sidescan sonar data of ripples off on the west Florida shelf were collected as part ...
Acoustic scattering of broadband echolocation signals from prey of Blainville's beaked whales : modeling and analysis
(Massachusetts Institute of Technology, 2006)
Blainville's beaked whales (Mesoplodon densirostris) use broadband, ultrasonic echolocation signals (27 to 57 kHz) to search for, localize, and approach prey that generally consist of mid-water and deep-water fishes and ...
Emulating the fast-start swimming performance of the Chain Pickerel (Esox niger) using a mechanical fish design
(Massachusetts Institute of Technology, 2006)
Mean maximum start-up accelerations and velocities achieved by the fast-start specialist, northern pike, are reported at 120 ms-2 and 4 ms-1, respectively (Harper and Blake, 1990). In this thesis, a simple mechanical system ...
