Cartographic Features of Central Gulf of Alaska 

About 96,000 cartographic features such as rocky reefs, kelp beds, rocks, islets and others were proofed, edited and digitized from the smooth sheets and charts. The most common feature was kelp beds (it should be noted that kelp beds are seasonal and their size and location are variable from year to year). The second-most common feature was rocks, at just less than 29,000, with the majority occurring in the Kodiak, Kenai and Sitka areas. Rocky reefs were third in occurrence, and there were 15,000 islets almost equally split between western and eastern sides of the CGOA.
