50 Years: The Department of Boating and Waterways, 1957 to 2007
the U.S. Navy. His photos offered a wonderful snapshot in time, but
did not provide a quantifiable tool for calculating beach and bluff
erosion rates. Later, the department would use high-resolution,
vertical aerial photography that allowed more accurate estimates
of beach and bluff erosion.
In the early 2000s, Gary Griggs, Ph.D., Professor of Earth and
Planetary Sciences and Director of the Institute of Marine Sciences at
UC Santa Cruz, requested copies of George Armstrong’s early photos
for his graduate students who were studying beach and bluff erosion.
Dr. Griggs also wanted to place the photos in the campus library
for future public use. Cal Boating was delighted to see this resource
utilized, especially since another state agency had the desire to use
and house the collection.
In 2002, Dr. Griggs asked Cal Boating if Kenneth and Gabrielle
Adelman could utilize the photo database for a 30-year time
comparison on the popular California Coastal Records Project
web site. The Adelmans had recently completed the same aerial
photographic survey performed by George Armstrong years
before. They restored the color balance of the original scanned
images, which had faded over time, utilizing computer Photoshop
methods and incorporated the photos into their web site (http://www.
californiacoastline.org). Now, Cal Boating’s 1972 and 1979 aerial
oblique photos can be accessed online and instantly compared to the
high-resolution coastal images taken by the Adelmans in 2002 and
2005, providing photographic documentation of 33 years of coastal
change in California.
Clean and Green Boating Campaign
Since 2004, Cal Boating has teamed with the California Coastal
Commission (CCC) to promote the Clean and Green Boating
Campaign. The “Clean and Green” campaign conducts boater
education statewide in partnership with many public and private
agencies that wish to instruct California boaters and marine
businesses about environmentally sound boating practices. The
campaign also supports the northern California and Sacramento-
San Joaquin Delta chapters of the California Clean Boating Network
(CCBN), originators of the
Changing Tide Newsletter
. This publication,
first disseminated in 1998, has become the widely recognized voice
Reilly The Rainbow Trout
was
used in posters that the Clean
and Green Boating program to
promote clean boating practices
and help ensure that clean
boating is part of the experience
on California’s waterways.
