attribute	NC_GLOBAL	acquisition_description	String	Collection & Larval Rearing \u00a0We collected adult Olympia oysters (Ostrea lurida) from Fidalgo Bay in June 2017 and maintained them in a sea table with continuous flowing seawater heated to 19-20\u00b0C at the Shannon Point Marine Center. We fed adult oysters were fed concentrated algae once a day (Shellfish Diet, Reed Mariculture) and utilized banjo-style filters (60-m) attached to the outflow pipes of the sea table to catch released O. lurida larvae. We then collected and reared larvae at 12\u00b0C in 3-L jars (2 individuals mL-1). Each jar of larvae received a 50% water change with 0.35-m filtered sea water and were fed Isochrysis galbana algae (50,000 cells mL-1) daily. \u00a0Experimental Design \u00a0To measure the effect of pH conditions on the vertical distribution of larvae we established three experimental pycnocline treatments within clear plexiglass water columns (2.5cm x 2.5cm x 30cm): (1) ambient water (400ppm) in the top layer and acidic water in the bottom layer (1500ppm), (2) ambient water (400ppm) in both top and bottom layers, and (3) acidic water (1500ppm) in the top layer and ambient water (400ppm) in the bottom layer. Each water layer was 60-mL of water and filled the column 10-cm high, so when each experimental treatment was established it filled the column to 20-cm. We established the experimental treatments by increasing the density of seawater in the bottom layer by 0.003-0.005 g ml-1 using PercollTM GE Healthcare (Podolsky & Emlet 1993). Experimental treatment water was kept at 12\u00b0C and pre-equilibrated to the desired pCO2 level and density. We also included blue food coloring (1 drop per 100-mL) to the dense bottom layer to more easily visualize the density layers while establishing experimental treatments. We set-up four replicate columns for each experimental treatment making twelve columns total per experiment. \u00a0On the day of each experiment, we incubated the experimental treatment columns in clear plexiglass water baths connected to a Fisher Scientific Isotemp recirculating water bath to maintain treatment temperature at 12\u00b0C throughout the experiment. We carefully injected 150 larvae by syringe into the bottom 2-cm of each column with no more than 2-mL of their culture water. Olympia oyster larvae are highly phototactic (personal observations), so larvae were kept in the dark and we video recorded their vertical positions under infrared light two times: the first time at 10 minutes of acclimation in the columns and the second time at 30 minutes of acclimation in the columns. To record, we used an infrared uEye camera equipped with Edmund Optics VIS-NIR Lens mounted on a motorized stand. We later counted by eye the number of larvae per centimeter area of each column from the videos.

attribute	NC_GLOBAL	projects_0_acronym	String	Climate stressors on larvae
attribute	NC_GLOBAL	projects_0_description	String	In the face of climate change, future distribution of animals will depend not only on whether they adjust to new conditions in their current habitat, but also on whether a species can spread to suitable locations in a changing habitat landscape. In the ocean, where most species have tiny drifting larval stages, dispersal between habitats is impacted by more than just ocean currents alone; the swimming behavior of larvae, the flow environment the larvae encounter, and the length of time the larvae spend in the water column all interact to impact the distance and direction of larval dispersal. The effects of climate change, especially ocean acidification, are already evident in shellfish species along the Pacific coast, where hatchery managers have noticed shellfish cultures with 'lazy larvae syndrome.' Under conditions of increased acidification, these 'lazy larvae' simply stop swimming; yet, larval swimming behavior is rarely incorporated into studies of ocean acidification. Furthermore, how ocean warming interacts with the effects of acidification on larvae and their swimming behaviors remains unexplored; indeed, warming could reverse 'lazy larvae syndrome.' This project uses a combination of manipulative laboratory experiments, computer modeling, and a real case study to examine whether the impacts of ocean warming and acidification on individual larvae may affect the distribution and restoration of populations of native oysters in the Salish Sea. The project will tightly couple research with undergraduate education at Western Washington University, a primarily undergraduate university, by employing student researchers, incorporating materials into undergraduate courses, and pairing marine science student interns with art student interns to develop art projects aimed at communicating the effects of climate change to public audiences As studies of the effects of climate stress in the marine environment progress, impacts on individual-level performance must be placed in a larger ecological context. While future climate-induced circulation changes certainly will affect larval dispersal, the effects of climate-change stressors on individual larval traits alone may have equally important impacts, significantly altering larval transport and, ultimately, species distribution. This study will experimentally examine the relationship between combined climate stressors (warming and acidification) on planktonic larval duration, morphology, and swimming behavior; create models to generate testable hypotheses about the effects of these factors on larval dispersal that can be applied across systems; and, finally, use a bio-physically coupled larval transport model to examine whether climate-impacted larvae may affect the distribution and restoration of populations of native oysters in the Salish Sea.
