IMPROVED METHODS FOR VISUAL AND PHOTOGRAPHIC BENTHIC SURVEYS
visual photographic survey methods benthic biology
2009/5/6
As funding for field work becomes more competitive, it is increasingly important to produce cost effective quantitative results using calibrated methods. Much effort is devoted to visual and photogra...
DIVER-OPERATED INSTRUMENTS TO MEASURE COASTAL BENTHIC OPTICAL PROPERTIES

2009/5/6
The Office of Naval Research has embarked on a long-term project, Coastal Benthic Optical Processes (CoBOP), with the goal of better understanding how light interact; 5 with the shallow ocean floor. ...
AN INSTRUMENTED LANDER FOR MEASUREMENT OF BENTHIC RESPIRATION AND PRODUCTION
oxygen Benthic method
2009/5/6
In situ measurement of oxygen exchange at the sediment-water interface is desirable for many aquatic studies but logistically challenging. A new benthic lander constructed with inexpensive, off-the-s...
