An Oceanographer's Holiday to the Bermuda Triangle

by W. Sean Chamberlin, Ph.D.

Introduction

This Flash presentation documents a research expedition in which I participated in January 2002 at the invitation of the chief scientist, Dr. Maureen Conte of Bermuda Institute of Ocean Sciences . Her research, part of the Oceanic Flux Program (OFP), funded by the National Science Foundation Division of Ocean Sciences, aims to understand the physical, chemical, geological and biological factors that affect the flux of biogeneous particles and their chemical elements to the deep sea and the sea bottom. This research is vitally important for determining the role of the oceans in the global carbon cycle, for understanding the ecology of food webs in the near-surface and deep waters of the ocean and for interpreting the sedimentary record of deep-sea sediments and the ecology of deep-sea benthic communities.

My role in the expedition included assisting with the mechanical and scientific operations of retrieving and deploying a two-and-a-half-mile "instrument" and its samples, i.e. a deep-sea sediment trap mooring, documenting the research for dissemination to college-level introductory oceanography classes and staying out of the way when cable and shackles and floats were sliding across the deck in rough weather. The research took place aboard the R/V Weatherbird II, a Univeristy-National Oceanographic Laboratory System (UNOLS) vessel stationed at the Bermuda Institute of Ocean Sciences. The site of our operations, the OFP mooring site, has provided the longest continuous record of sediment fluxes in the ocean anywhere. That makes it pretty important.

The original presentation, composed in Powerpoint and presented as a seminar on campus, exceeded a reasonable size for web presentation. A web-based version was published on this site, but it lacked the auto-run feature and the music. Now, with the release of Flash MX in Summer 2002, the presentation in its entirety can be enjoyed by all.

The primary goals of this presentation are:
