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...
