SBC LTER: Time series of settlement of urchins and other invertebrates

The dataset comprises weekly to biweekly data on invertebrate
settlement on artificial substrates at six sites in Southern
California, and one site in Northern California. The study began in
early 1990 and is ongoing. The study’s main focus is on urchins
( Strongylocentrotus purpuratus and Mesocentrotus franciscanus ), but was expanded to
include selected bivalves, gastropods and crabs during the period
1994-1997. The purpose of the study is to compare and contrast patterns of
settlement supply across a large geographical gradient to explore the
possible influence of oceanographic features on these patterns. Both
of these goals are facilitated by the long duration of the dataset,
its large geographical range and the high temporal frequency of
collection.
