Subject: (Interview). Subtitle: Ken Sherman. Timecode In: 00:00:34. Timecode out: 00:24:26. Notes: Fisheries. Equipment Notes: Stereo=1; Split track. Log: AC interview of Dr. Ken Sherman :40 KS My name is Ken Sherman I work with the National Marine Fisheries Service. I do work on large marine ecosystems, and deal with the interaction between fisheries and their ocean environment, and fisheries and people who use fish for economic purposes: fisherman and people dealing with other marine resources other than the sort of ordinary fish we know about, but people who are interested in marine algae, seaweeds, um, invertebrates, organisms living on the bottom. We actually have an interest in the wide spectrum of living marine resources in the populations that constitute these resources. AC 1:35 When you say fishery -when people use the word fishery, what do they mean? KS 1:39 They generally mean an activity that has an economic end result, in contrast to a more scientific perspective which would have to do with the actual demographics of the populations that constitute the resource. AC 2:01 OK. Those were just little things to start with.... Describe if you would the northeast shelf ecosystem. When you call that great area a northeast shelf ecosystem what exactly do you mean. What is it? KS 2:21 Well, off the coast of the United states we are very fortunate in having very productive coastal waters. Not all coastal waters are identical. They have distinct characteristics and they can be separated on a regional basis on their natural productivity, on the bottom contours -a criteria we call bathymetry -and in the nature of the interaction between the water column itself and the current, something we refer to as hydrography, and then the linkages in the food chain between the various components in the food chain: plankton, fish, marine mammals, marine birds. There are distinct associations around the U.S. and in observing these distinct associations we've been able to apply scientific ecological criteria and have divided the area into seven large marine ecosystems and they extend pretty much over two hundred thousand square kilometers -each of them. And then in the northeast, we have an area that extends from Canada to the North and to Chesapeake Bay, and the South and from inshore to about two hundred miles off shore. And we refer to this as a distinct large marine ecosystem and we simply use the description of northeast continental shelf ecosystem for this region. AC 4:03 You say that there are seven of these regions that layoff the coast of the United states? KS 4:08 Yes, that's correct. AC 4:10 Are these different regions that you could see on a map? .. KS 4:24 Yes, we actually have actually over the past ten years atlas projections of these areas. And the one I just described briefly is the northeast shelf ecosystem from Chesapeake Bay to the Florida straits we have another distinct system that we refer to as the southeast shelf system. Adjacent to that is the entire Gulf of Mexico as a large marine ecosystem. On the west coast we are looking at a very broad area off the coast of California referred to as the California Current large marine ecosystem. And the area to the north of the that off the coast of Washington and Oregon is the Gulf of Alaska large marine ecosystem. And just to the north and west of that is the Bering Sea ecosystem, and out in the central Pacific we look at clumps of Ireland as insular large marine ecosystems and the one that we are most interested in in this country is of course the Hawaiian Islands as an LME, large marine ecosystem. AC 5:31 NOW, did you come up with this idea of these large marine ecosystems? Because I haven't -these are not commonly -people don't think that there are geographical demarcations off the coast of the -we don't think of that as something that's applying to th...
