Weights of northern elephant seal weanlings from Año Nuevo Reserve

Long-term observations of foraging success at
the population scale are key to understanding
demographic and ecological patterns.  Northern elephant seals,
Mirounga angustirostris, are capital breeders and the resources
delivered to the pup during the 4-week lactation period are related to
both the past foraging success of the mother and the future survival of
the pup post-weaning.  We collected weight and basic morphometric
data from more than 7,000 recently weaned elephant seals at the
Año Nuevo colony in central California, USA beginning in 1976 and
extending through the present.  This archive will be updated
periodically as new data are collected. The PIs would like to be informed
of manuscripts intended for publication that use this dataset. Depending
on our level of interest and how much a paper depends on the data,
co-authorship might be requested. Funding for this project was
provided by a variety of public and private organizations
including:  NSF, ONR, JIP, and the Moore, Packard and Sloan
foundations (please consult PI's for a complete list). 
Funding was also provided by generous donations to Año Nuevo
Reserve and UC Santa Cruz.
