Good shot there Art, problem with pilings most don't last longer than a few
years , a hundred at the most and concrete pilings were generally not used
until the 1960's. Glacial deposits are the best records even though they
don't freeze sea water they do record the various climatic changes some as
far back as 10's of thousands of years. These same deposits also trap
atmospheric gases so as to record CO 2 levels, another indicator of climatic
conditions.  Well I better jump off before i get to far from the topic.
