Pteropod adult (>0.5 mm, with fully developed wings/parapodia) were captured for experiments using a Reeve net with 333-m mesh and a large cod end that was deployed at slow speeds, for a short duration (< 1 h) with the aim of gently sampling live, undamaged specimens on various cruises. Tows were conducted at multiple stations in the Gulf of Maine (C42 22.1’ - 42 0.0’ N and 69 42.6’ - 70 15.4’ W). Individuals for respiration experiments were returned via coolers to a walk-in cold-room facility at the Woods Hole Oceanographic Institution within 8 h of collection. The cold-room was set at a constant temperature of 8C for all experiments. During each experimental period, water had been collected from an offshore site concurrent to pteropod sampling and had been returned to the lab in advance for filtration (0.2-m) and thermal equilibration. It had been bubbled with ambient air, which ranged from a calculated 380 to 440 atm over the seasonal cycle, for ~12 h prior to the arrival of the pteropods. Upon arrival, pteropods were placed in 1-L beakers of water containing the filtered in situ water (15 ind L-1) for 8-12 h to allow for further temperature acclimatization and gut clearance. After this period, healthy looking individuals (actively swimming or with parapodia extended) were placed into glass respiration chambers (containing optode spots; OXFOIL: PyroScience, Aachen Germany) with 2-3 mL fresh 0.2-m filtered water. A control chamber, without a pteropod, was set up for every fourth chamber to determine background bacterial respiration. The oxygen concentration was measured non-invasively at the start of the experiment and 24 h later using a FireStingO2 optical oxygen meter (PyroScience, Aachen Germany). At the conclusion of the experiment, each organism was visually inspected to confirm survival, briefly rinsed with DI water, placed in a pre-weighed aluminum dish, and weighed on a Cahn microbalance (C-33; 1 g precision) for wet mass. They were then dried for 3-7 days in a drying oven at 60C and weighed again to obtain dry mass. Final oxygen consumption rates were calculated based on the change in oxygen between the final and initial oxygen measurements, corrected for the bacterial respiration from the control chambers (mol O2 h-1).
Sampling and analytical procedures:
Temperature in the experiments was continually monitored using the Pyrosciences temperature logger that comes with the Firesting meter and are reported for only the ~24 duration of the respiration experiments.
Carbonate chemistry parameters are calculated as the average (over the course of the whole 14 day experiment) of measured pH, DIC and TA values using CO2sys. To monitor the carbonate chemistry during the experiments, subsamples of water (50 mL) from each carboy were taken every 2–3 days and measured spectrophotometrically for pH as described in White et al. (2013). To more fully characterize the carbonate chemistry of the experimental treatments, discrete samples for analysis of dissolved inorganic carbon (DIC) and total alkalinity (TA) were also collected from the pre-equilibrated water at weekly intervals, prior to its transfer to the carboys (day 0 and 7) and from the water in each carboy right before it was replaced during water transfers (day 7 and 14). This provided both the starting and ending DIC and TA of each batch of water for the first two weeks, and the starting conditions for week 3. DIC was measured using an Apollo SciTech DIC auto-analyzer, while TA was measured using an Apollo SciTech alkalinity auto-titrator, a Ross combination pH electrode, and a pH meter (ORION 3 Star) based on a modified Gran titration method (detailed in Wang et al., 2017). pH is reported on the seawater scale (pHsw). Salinity was measured with a Hannah refractometer.

Seasonal and Ontogenetic Effects of Ocean Acidification on Pteropods in the Gulf of Maine
http://www.whoi.edu/people/glawson/
Seasonal and Ontogenetic Effects of Ocean Acidification on Pteropods in the Gulf of Maine
<p>This project will involve a series of five short cruises in 2013 and 2014, during which a variety of hydrographic, chemical, and biological data and samples will be collected, as well as a number of laboratory experiments examining pteropod physiology and gene expression.</p>
<p>From NSF proposal abstract:</p>
<p>Dissolution of excess anthropogenic CO2 into the ocean is causing the marine environment to decrease in pH. This "ocean acidification" is predicted to threaten a broad variety of marine organisms, particularly calcifying animals such as the thecosome (i.e., shelled) pteropods. These pelagic gastropods form an aragonite shell, are prey for a number of commercially important fish, and are significant contributors to carbon biogeochemistry. Their ecosystem importance, abundance, and sensitivity to dissolution position them as an important group for investigating the impacts of acidification. Our understanding of the effect of high CO2 on pteropods and the pelagic ecosystem, however, is limited primarily to short-term studies of adult calcification and respiration response in the polar ecosystems. There have been no seasonal studies of sensitivity and our understanding of the effect of CO2 on pteropod early life stages is limited. Limacina retroversa is a particularly abundant thecosome pteropod in the North Atlantic, where it is prey for a number of fisheries species and other top predators. This species is also the most common pteropod in the Gulf of Maine (GoM) where it is present year round. L. retroversa thus offers the prospect of a useful model pteropod species, given both its ecological importance and its abundance in readily accessible waters. The investigators will conduct a series of short cruises to sample L. retroversa on a seasonal basis from local waters of the GoM near Cape Cod. The carbonate chemistry of the GoM fluctuates seasonally, providing the opportunity to assess the response of wild caught pteropods to natural changes in CO2. By characterizing the carbonate chemistry of the water column and measuring the metabolic rate, shell quality, and gene expression of pteropods throughout the year, the researchers will achieve a time series of pteropod sensitivity to CO2. Subsequently, using experimental manipulations the investigators will explore the effect of seasonal acclimation on pteropod response to short- and medium-term exposure to enhanced CO2. Pteropods frequently lay eggs in captivity, and at WHOI there is institutional expertise in maintaining these individuals in the laboratory. Building on these strengths, the researchers will also study the effect of CO2 on embryonic and larval development in L. retroversa. These earliest life-stages of marine calcifiers are thought to be especially sensitive since initial shell precipitation and the highly energetic processes of growth and development are impeded by CO2 exposure. They will also document mortality, shell production, abnormality, and developmental rate of clutches of pteropod embryos exposed to increased CO2.</p>
<p>Intellectual Merit: Thecosome pteropods are an abundant group of calcifying zooplankters that have been chronically understudied, particularly in temperate regions. Due to its accessibility and ecological importance, L. retroversa can be developed as a valuable model, interesting both as the dominant pteropod in the commercially-important GoM region and also an abundant pteropod in the temperate waters of the North Atlantic. The goal of this research is to augment our knowledge of the distribution of L. retroversa, to attain an understanding of their seasonal sensitivity to natural variability in CO2, and to see how this exposure impacts responses to both short- and medium-term CO2 exposure. Using powerful transcriptomic technologies, the research will transform our understanding of this group by investigating the molecular mechanisms of response in L. retroversa to both seasonality and varying durations and intensities of acidification, contextualized by ecosystem- and organism-level metrics. Furthermore the study will examine the effect of CO2 on the eggs of pteropods for the first time, providing insight into their sensitivity to an acidifying environment.</p>

This MATLAB code converts an image (.jpg) of a pteropod shell take with a stereomicroscopoe and calculates the transmittance (images taken with light from below) or opacity (images taken with lighting from the sides) . The code identifies shells against the white background by thresholding the image to black and white. The aperture as well as any holes or dark areas resulting from remaining tissue are then manually cropped from the object. The transmittance was calculated as the mean grayscale value (range: 0-255) of the pixels of the shell divided by 255 to get a scale of 0 (black) to 1 (white), while opacity is calculated in the opposite fashion 1 (black) to 0 (white).

The net is lowered to a particular depth and then hauled slowly back to the surface (5-10 m/min). Reeve (1981) also described a double net system with no bridle and flotation at the net mouth that is attached to a roller mechanism that rides on a tow wire.
The roller system is locked in place by a pressure release device. Once below a set pressure, the roller
and nets are released and they float slowly up the wire, gently collecting the zooplankton, without being
influenced by the motion of the vessel and associated vertical wire movements. (from Wiebe and Benfield, 2003) Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/NETT0147/
