About CoML Logbook Data

The data presented here were collected as part of the History of Marine Animal Populations project, within the Census of Marine Life project.

They include daily information on the location of whaling vessels throughout individual voyages, from a sample of logbooks kept on board individual vessels. Included are location, whaling activity, encounters with whales, including numbers seen, struck, and landed, and the products obtained.

Daily whaling data were extracted from a sample of whaling logbooks by a team of scientists and historians during the Census of Marine Life project between 2000 and 2010. The data include information on the location of whaling vessels and whales seen or caught from the late 18th to early 20th centuries.
