Study the Science: Physical Oceanography

The primary objective of the physical oceanography study is to describe spatial and seasonal characteristics of the water masses and circulation in the northeastern Chukchi Sea. Data are collected through instrumentation on the vessel. CTD (conductivity-temperature-depth) casts are made at each station. The CTD includes a fluorometer (as an index of chlorophyll biomass) and a transmissometer (as an index of water-column turbidity.) Water samples are also collected and analyzed for nutrients and chlorophyll. Another primary instrument, a vessel-mounted ADCP (Acoustic Doppler Current Profiler), provides an estimate of the water-column current structure and its spatial and temporal variability.

Interesting Fact:
In summer, ocean currents often run eastward or northeastward at depth and at the surface at Klondike. This flow tends to bring warm, moderately salty water into Klondike and the southwest portion of Burger from the Central Channel area. Under moderate westward winds that flow is eastward, although under strong westward winds that flow is reduced or reversed.
