Phase II

SBI Phase II (2002-2006) constituted the core regional field investigations in the Chukchi and Beaufort Seas, along with regional modeling efforts. The first field program began in the spring of 2002. The principal study area was the outer shelf and continental slope area of the Chukchi/Beaufort Seas. The SBI Phase II field project is centered around three research foci in the core study area in the Chukchi and Beaufort seas:

  1. Northward fluxes of water and bioactive elements through the Bering Strait input region
  2. Seasonal and spatial variability in the production and recycling of biogenic matter on the shelf- slope area
  3. Temporal and spatial variability of exchanges across the shelf/slope region into the Canada Basin.

The main focus area for shipboard work is planned for the outer northern shelf and slope of the Chukchi and Beaufort Seas (Figure 3). The SBI II field program will include four process-oriented cruises in May/June and July/August 2002 and 2004 (Table 1). Alternate years, 2003 and 2005 in both May/June and July/August, will include reduced field programs for critical time-dependent, core measurements essential for interpreting processes relevant to shelf-basin interactions and ecosystem response. Annual fall cruises will occur in September and will provide an opportunity for emplacement of new SBI time series moorings into the SBI mooring network, underway surveys, and opportunities for coring.
