The
diverse processes that link the seafloor to the overlying ocean range
from feeding mechanisms of individual suspension feeders such as
sponges and bivalves through the behavior pattern of ground fish and
migratory zooplankton to the interplay between hydrodynamics and the
benthos (the bottom of the sea). Fieldwork and the development of new
methods for underwater studies are major themes in my work.
Current
research:
Nutritional
ecology of
suspension feeders
Capturing
particles suspended in the water is a
unique feeding strategy
for aquatic animals. My studies focus on measuring the metabolism, diet
composition, feeding preferences, and feeding rates of marine
suspension feeders. I am particularly interested in developing
underwater (in situ)
methods which facilitate the study of
undisturbed animals in their natural environment. Read more...
Sediment
resuspension by fish
Benthic
(ground) fish resuspend large amount of sediments while foraging and
seeking for shelter. We discovered that fish activity alone could
maintain a layer of turbid water near the bottom (nepheloid benthic
layer), enhance the transport of nutrients and benthic oxygen demand,
and considerably reduce organic carbon sequestration. Currently, we are
developing tools that will allows us to quantify these processes and
understand their effects in different marine habitats. Read more...
Benthic-pelagic
coupling
Benthic
organisms are dependent on hydrodynamics and other processes at the
water column for every aspect of their life history. In many cases, the
activity of benthic communities can also control water column
processes. We are using a variety of methods to quantify these process
in the field. Read more...
