CoML Daily vessel locations

This table from logbook entries includes information from logbooks from American offshore whaling voyages. These data were extracted from the original whaling logbooks during a scientific research project conducted by a team from the Census of Marine Life project (CoML, www.coml.org) led by Tim Denis Smith between 2000 and 2010.

Information about the content and structure of the database is available in the Database Description and the Column Definitions, Code Tables and Usage Notes. We plan on updating the database annually. You are encouraged to submit additions and corrections through the submission form.

Small subsets of the data may be printed or downloaded directly from the table below. Read The Data Viewer Interface for instructions. For research purposes, the complete database may be downloaded for processing on your local computer.
