Two great pages with lots of Walrus info, and in the case of the USGS, the Pacific Walrus International Database (PWID), described as:
The Pacific Walrus International Database (PWID) is a comprehensive set of Pacific walrus biological data collected by several participating organizations in the Bering and Chukchi Seas. Data compilation was focused on abundance and distribution data, however, other types of data are included. Data categories include: land and ice haulout counts, sex/age composition, reproduction, mortality, harvest statistics, and morphometry. As of September 1998, the database includes reference to 33 data sets. The PWID includes metadata for every data set, but for some data sets the data may have been retained by the data owner.
There are a lot of research-oriented walrus resources here. Note being familiar with this type of government-run site, I’m impressed with the amount of data available. Looks like a solid resource for anyone whose interest in Walrus requires some deep data.

If your interest runs more towards conservation and endangered species concerns, you should visit the Pacific Walrus page at the Center for Biological Diversity. Here is the mission statement from their website:
At the Center for Biological Diversity, we believe that the welfare of human beings is deeply linked to nature — to the existence in our world of a vast diversity of wild animals and plants. Because diversity has intrinsic value, and because its loss impoverishes society, we work to secure a future for all species, great and small, hovering on the brink of extinction. We do so through science, law, and creative media, with a focus on protecting the lands, waters, and climate that species need to survive.
