  • List of Available Photographs by Data, Appendix A in Humboldt Bay, California, Entrance Channel. Report 1: Data Review (Costa and Glatzel) 2002 (print copy available in TC 225 H8 C67 2002 Hum Co Coll). Lists by date (with the earliest imagery being 1931) aerial photography that includes Humboldt Bay. Metadata is included for each flight along with location of availability. The overall report provides an inventory and review of historical and recent data describing Humboldt Bay and the adjacent littoral cell. The review was prepared for the US Army Corps of Engineers Coastal Inlets Research Program (CIRP) study of the Humboldt Bay entrance.

  • Northern California Coastal Photography, Beach Profile and Bathymetry Index (U.S. Army Corps of Engineers) 1987 (print copy available in Ref GB 458.8 N67 1987) Inventory of central and northern California coastal aerial photography, bathymetric surveys, beach profiles, and shoreline changes available from the U.S. Army Corps of Engineers, San Francisco District; and other federal and state agencies. Appendix A reproduces "An Index to Historical Hydrographic and Topographic Charts of the California Coast Located in the Files of the State Lands Commission. Photographs and beach profiles from the corps were compiled to document dimensions and beach characteristics, historic shoreline changes, effects of storms and structures on the beach, and significant beach and inlet changes.
