Bromine Air-sea Cruise Pacific (RB-99-06) (1999)
The RB-99-06 (BACPAC 99) cruise was conducted in the North Pacific Ocean between September 14, 1999, and October 23, 1999. The cruise departed from Kwajalein, Marshall Islands, and ended in Seattle, Washington, with port stops in Oahu, Hawaii, and Dutch Harbor, Alaska. The primary objectives of the cruise were the deployment and recovery of several moorings, including moorings in support of the NOAA Real Time Tsunami Warning system and other buoys that measure various physical and chemical properties.
We measured halocarbons concentrations in the air and seawater as a
piggyback operation on this cruise. This cruise track did not specifically
cross regions where halocarbons had been previously measured. However,
the fact that these measurements were made in the fall does complement
the summer measurements from the GasEx 98 field campaign. Open ocean
methyl bromide undersaturations measured in the North Pacific Ocean are
consistent with previous observations, as well as a seasonal cycle in temperate
waters. Methyl bromide observations from this cruise are expected
to be published in 2002-2003.
