Although this year's fieldwork has been relatively quiet
compared to the past few years, the Sediment Transport Group(STG)
is still involved in many projects and activities:
Massachusetts Baby Long Term Monitoring Program
Ongoing projects include the data that we collect to monitor
the Massachusetts Water Resources Authority's new sewage
outfall pipe for Boston. We deploy a mooring and a tripod
near Boston and a mooring and a tripod off the coast of
Scituate. These measurements have been continuous over the
As follow-up to the Monterey Canyon deployment ending in
December 2003, two moorings were deployed in May 2005. The
STG is designing the moorings and preparing most of the
instruments and equipment which was deployed by the USGS
Menlo Park office. These moorings consist of Anderson sediment
traps, Microcats, Seacats, Branker data loggers, transmissometers,
and Worhorse ADCP's.
Martha's Vineyard Coastal Observatory
The STG is currently designing platforms and instrumentation
to be deployed off the coast of Martha's Vineyard in September,
2005. Some of the focuses of this project are to compare
the results serveral suspended sediment sensors, and test
a developing recovery system for tripods.
Other Fieldwork Support
The STG is providing instrumentation support to many projects
in the following areas: Seagrass-Puget Sound, Hood Canal,
San Gabriel River, and San Fransisco Bay.
Sontek Hydra Toolbox
The STG is continuing development of a MATLAB toolbox for
the Sontek Hydra data loggers in order to provide clean,
accurate data to sediment transport modelling efforts. This
toolbox will be similiar to the one that the STG developed
for the ADCP.
Underwater Camera System
The STG continues to develop a time-series still camera
system to replace exsisting camera systems that are mounted
on benthic tripods. Two prototype systems have been tested
At the request of Massachusetts Water Resources Authority(MWRA),
the STG continues to evaluate new flourometer technology
for its suitability for their applications.
Tripod Recovery System
To reduce the number of times tripods must be recovered
by divers or ROV, the STG is developing a new recovery system
that won't be deterred by fouling trawling, tipping, and
storm related problems.
Metadata, Data Archival and Processing Training Session
The STG is providing a training module for metadata collection,
ADCP processing, and data archival to personnel from several
other USGS field offices in August 2005.
The STG personell is attending the OCEANS conference in
Brest France, and Current Measurement Technology Conference
in Southampton, United Kingdom in June 2005.
