http://www.postcoml.org/Dr. David Welch reviews the technical operation of the Pacific Ocean Tracking Project (POST) and reviews its performance in addressing key policy questions.
Abstract
Pacific Ocean Shelf Tracking (POST) array, currently operates as the world’s largest telemetry system for studying the movements and survival of marine fish. It will provide the exemplar for the Ocean Tracking Network (OTN), the subject of the May 18th talk by Ron O’Dor. OTN shall form “an array of POST arrays," sitting on the continental shelves of all the continents on the planet. As such, it provides a prime example of what the evolving Ocean Observation System (OOS) system might look like.One of the Census of Marine Life’s (CoML's) original field projects, POST made a natural fit given the CoML’s focus on distribution, diversity, and abundance of marine life. However, POST has begun to prove itself in addressing key US policy questions for fisheries, and thereby demonstrating the fundamental linkage between these biological questions and vexing high-level policy issues. POST thus forms an interesting example of how the development of a highly quantitative tool looking at basic biological processes can inform and reinvigorate the science of fisheries management—and ocean research.The operational considerations involved in developing POST include the need for:
Developing large-scale and high volume methods for conducting surgery on thousands of test animals while ensuring the highest ethical standards of fish handling and surgical procedures are met.
Developing technical methods for deploying and maintaining a very large scale permanent tracking array on the seabed.
Ensuring that the data are recovered in very high yield to validate the array concept and provide meaningful scientific results to justify the support for building (and expanding) the array.
Dr. Welch reviews the technical operation of POST from the twin perspectives of ethical animal use and technical operation of a large-scale engineering system. In the final section of the talk, he reviews the performance of the array in addressing key policy questions concerning the management of Columbia & Fraser R salmon populations.
Biography
David Welch received a B.Sc. in Biology and Economics from the University of Toronto and a Ph.D. in Oceanography from Dalhousie University (Halifax, Nova Scotia) in 1985.
He started and led the Canadian government’s High Seas Salmon Program at the Department of Fisheries and Oceans (DFO) in 1990, after a quarter century of governmental hiatus in ocean research on salmon. During the next decade he studied the ocean biology of Pacific salmon, and provided some of the first compelling evidence for a potentially profound impact of global warming on Pacific salmon in the ocean.
Dr. Welch serves as the chief architect of the Census of Marine Life’s project POST and President of Kintama Research. Welch started Kintama in 1990 to develop the pioneering technology platform necessary for delivering data from a permanent ocean array capable of directly measuring survival of migrating fish in the ocean.
We can measure the success of POST from three perspectives:
It is the largest and most complex marine tracking array under single management anywhere in the globe, with a current geographic span of almost 2,500 km;
The Canadian Government committed $45M Cdn starting in 2007 to champion the globalization of the POST array as the Ocean Tracking Network;
The array is now capable of measuring the movements and survival of fish as small as 12.5 cm year-round, and may be capable of tracking fish as small as 10 cm by 2008.
As a result, the marine science community stands on the brink of having the ability to conduct direct quantitative experimental studies in the ocean on fish of the kind that transformed chemistry and physics one and two centuries ago.
Dr Welch has previously acted as scientific spokesman for the World Wildlife Fund on the issue of global warming, and received an invitation to testify on the results of his research on the ocean biology of Pacific salmon in the U.S. Senate. Dr Welch speaks fluent Japanese and lives on Vancouver Island in Nanaimo, British Columbia.
