As the workhorse of toxic pollution research, the
research vessel Harold W. Streeter routinely spends over
100 days a year collecting sediment and fish samples
from embayments of Puget Sound and beyond. The
deck of the Streeter, with its round-bottom hull,
provides a rolling research platform that requires
onboard scientists to have good sea legs.
Designed by Edwin Monk, a Seattle designer known
for his adaptation of traditional fishing vessel designs
to recreational powerboats, the Streeter was built in
1962 to conduct water quality sampling on the Colum-bia
and Willamette Rivers in Portland, Oregon for the
U.S. Office of Public Health. The Northwest Fisheries
Science Center acquired the vessel in 1973 to study the
impacts of toxic pollutants on local fishery resources,
protected species, and marine habitat.
Originally powered by an engine designed and built in
1942 as a World War II landing craft engine, the Streeter
had a governor that allowed two maximum operating
speeds: one for normal and one for battle operation.
After 33 years of reliable operation (albeit not at battle
speed), the Streeter was re-powered in 1995.
The Streeter has undergone several environmental
upgrades over the decades. It is equipped with a
system which filters out oily waste that may have
accumulated in the bilge prior to pumping the bilge
water overboard, and a vapor-trap system which
captures and recycles oil vapors created while the
engine is running. The vessel also has a 50-gallon
holding tank and disposes or recycles much of the
jetsam collected from fish trawls.
A holding tank and coolers can receive live fish
specimens, which are typically transported to the
Center’s field station at Mukilteo. A wet lab in the
cabin is used to weigh, measure, and dissect specimens
needed for tissue samples. Tissue and sediment
samples are preserved and returned with the Streeter to
dock at the Center’s Montlake Facility along Portage
Bay. Scientists at the Montlake laboratories conduct a
variety of biological and chemical analyses to deter-mine
the presence of toxic contaminants and the status
of the specimens’ health.
Sporting port and starboard aluminum booms
equipped with blocks, tackle, and two winches, the
Streeter can operate a sediment grab (a claw-like shovel)
to collect contaminants in bottom sediment. The grab
scoops up sediment a foot deep while leaving the thin,
top layer undisturbed for accurate contaminant
sampling. The boom also is used to tow small experi-mental
trawls (nets) to collect bottom fish such as English sole and rock sole.
But the trawls have caught more than fish. Over the
years, the Streeter has hauled up logs, tires, 50-gallon
drums, plastic chairs, abandoned gillnets and crabpots,
and a rickshaw bicycle. More interesting items hauled
onboard have included an Ernie puppet with barnacles,
a high-heel shoe (which the crew fondly named "True
sole"), and a dental bridge with four teeth.
Aside from amusing trawl captures, the Harold W.
Streeter has been a cornerstone in the Northwest
Fisheries Science Center’s evaluations of impacts and
remediation efforts needed in urban embayments on
both U.S. coasts.
The Streeter has been the backbone of our ability to
conduct environmental assessments, allowing the
Center to become a national leader in expertise on the
impact of toxic pollutants on marine fish and their
habitats.
