We tested whether the thecosome pteropod Limacina helicina from Puget Sound, an urbanized estuary in the northwest continental US, experiences shell dissolution and altered mortality rates when exposed to the high CO2, low aragonite saturation state (Omega a) conditions that occur in Puget Sound and the northeast Pacific Ocean. Five, week-long experiments were conducted in which we incubated pteropods collected from Puget Sound in four carbon chemistry conditions: current summer surface (460-500 µatm CO2, Omega a=1.59), current deep water or surface conditions during upwelling (760 and 1600-1700 µatm CO2, Omega a=1.17 and 0.56), and future deep water or surface conditions during upwelling (2800-3400 µatm CO2, Omega a=0.28). We measured shell condition using a scoring regime of five shell characteristics that capture different aspects of shell dissolution. We characterized carbon chemistry conditions in statistical analyses with Omega a, and conducted analyses considering Omega a both as a continuous dataset and as discrete treatments. Shell dissolution increased linearly as aragonite saturation state decreased. Discrete treatment comparisons indicate that shell dissolution was greater in undersaturated treatments compared to oversaturated treatments. Survival increased linearly with aragonite saturation state, though discrete treatment comparisons indicated that survival was similar in all but the lowest saturation state treatment. These results indicate that, under starvation conditions, pteropod survival may not be greatly affected by current and expected near-future aragonite saturation state in the NE Pacific, but shell dissolution may. Given that subsurface waters in Puget Sound's main basin are undersaturated with respect to aragonite in the winter and can be undersaturated in the summer, the condition and persistence of the species in this estuary warrants further study.

This layer is a georeferenced raster image of the historic paper map entitled: Reconnaissance of Duwamish Bay & Seattle Harbor, Washington Ter., by the hydrographic party under the command of Lieut. James Alden, U.S.N. Assistant; redd. drng by J. R. Key; engd. by Apps. J.J. Knight & F. W. Benner. It was published by the U.S. Coast Survey in 1854. Scale 1:40,000. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Washington State Plane North Coordinate System HARN NAD83 (in Feet) (Fipszone 4601). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows coastal features such as channels, points, coves, islands, bottom soil types, flats, and more. Depths shown by soundings. Includes note. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

This layer is a georeferenced raster image of the historic paper map entitled: Seattle Harbor : Puget Sound Washington territory, issued May 1870 C.P. Patterson, superintendant; verification J.E. Hilgard, assistant in charge of the office; triangulation by J. S. Lawson assistant in 1874 based upon the primary triangulation by George Davidson, assistant in 1855-6; topography and hydrography by J.S. Lawson, assistant in 1874 & 5; resurvey of city of Seattle and water front by assist. J.J. Gilbert in 1886; additions by asst. Pratt in 1889; verifications of hydrology by Lieut. Comdr. W. H. Brownson U.S.N. inspector of hydrography. It was published by United States Coast and Geodetic Survey in July 1889. Scale 1:20,000. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Washington State Plane North Coordinate System HARN NAD83 (in Feet) (Fipszone 4601). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows coastal features such as lighthouses, rocks, channels, points, coves, islands, bottom soil types, flats, wharves, and more. Includes also selected land features such as roads, railroads, drainage, land cover, selected buildings, towns, and more. Relief shown by contours and spot heights; depths by soundings. Includes notes, tables, and list of authorities.
