| Title: | The impact of ocean acidification on the early life stages of surf clams and the interactive effects of feeding and temperature from laboratory experiment studies from 2011-07-12 to 2012-06-17 (NCEI Accession 0123314) |
| Abstract: | This dataset contains laboratory experiment data that were collected to examine the effects of ocean acidification on the Atlantic surfclam, Spisula solidissima, a species worth $31 million in 2009. Ocean acidification has negatively impacted growth and survival of multiple bivalve species, but because each species and developmental stage can show different responses, these studies were designed to determine potential impacts of increased CO2 on the larvae of the commercially important surfclam. Additionally, the role of nutrition (i.e., phytoplankton concentration) was included in a portion of these experiments because food availability may be able to mitigate the stress of ocean acidification and because ocean acidification has the potential to impact marine phytoplankton communities. During the summer of 2011, three different experiments were conducted at Woods Hole Oceanographic Institution examining the effects of three different pCO2 concentrations on larval surf clams. Two short term experiments (~70h) examined the effect of food availability on early shell development (fed vs unfed). One long term experiment (~21d) was conducted to examine the effects of pCO2 on shell development and metamorphic success (all animals well fed). Carbonate data is reported from these preliminary short-term experiments, and survival and shell length data is reported, in addition to carbonate data, from the long-term experiment. During 2012, one 6 day experiment was conducted examining the role and potential interactive effects of high and low food availability (400 and 40,000 cells ml-1 Tiso) and differential CO2 concentrations (ambient, ~1200 ppm and ~2200ppm). From these experiments, carbonate data, shell length, mass and biochemical compositions are reported. In 2013, two additional experiments were conducted to confirm results obtained in 2012. Unfortunately we observed stunted larval growth, no feeding effect on growth, high mortalities and a general failure to thrive. Given this, we infer poor gamete quality may have been the cause, and have chosen not to interpret these data as results are suspect. Therefore, 2013 data are therefore not included in this data submission. |
