Abundance of pelagic fish during the 19th and 20th centuries as recorded in anaerobic sediment off the Californias
Anaerobic sediment preserves a chronographic record of the bioclimatological conditions in coastal seas. Of the myriad elements within this record, the accumulation ofpelagic.fish debris is ofparticular interest. The deposition of scales of the Pacific sardine, the northern anchovy, the Pacific hake...
