Geophysical Research Letters 31:L06206. #------------------ # # Description & Notes: # Strait of Juan de Fuca Geoduck Clam Growth Data and SST Reconstruction. # Non-reconstructed SSTs given are the instrumental SST data for Race Rocks. Water # depth ranged from 8-20m. Growth data were obtained by extracting at least three # thin cross-sections from the hinge area of each shell. Digital images were captured # at magnifications ranging from 25-400x along a straight transect from the origin # of growth to the outer edge. Ring widths were measured perpendicular to the growth # line axis, and standardized using a modified negative exponential curve. Annual # growth indices were computed as the ratio of actual to modeled growth. To compute # the growth chronology, measurement series were averaged using a biweight robust # mean. Raw measurements can be found in the ftp directory for this data. # # Variables: # depth Depth (cm) # calyr calendar years BC/AD () # growin Growth Index- geoduck clams # sst-gcl Sea Surface
