WE'RE SWINGING ON ANCHOR this afternoon as powerful bursts of wind blow down through the Makua Valley and out to sea. The gales stop and start every 15 minutes, as abruptly as if a giant on the far side of the Hawaiian island of Oahu were switching a fan on and off. We sail at the gusts' mercy, listing hard to starboard, then snapping hard against the anchor chain before recoiling to port. The intermittent tempests make our work harder and colder. We shiver during the microbursts, sweat during the interludes, then shiver again from our own sweat.
I'm accompanying marine ecologist Kelly Benoit-Bird of Oregon State University, physical oceanographer Margaret McManus of the University of Hawaii-Manoa, and two research assistants aboard a 32-foot former sportfishing boat named Alyce C. On the tiny aft deck, where a marlin fisher might ordinarily strap into a fighting chair, Benoit-Bird and McManus are launching packages of instruments: echo sounders tuned to five frequencies; cameras; and a host of tools designed to measure temperature, salinity, current velocity, chlorophyll fluorescence, and zooplankton abundance, all feeding into computers lashed into the tiny forward cabin.
