Investigation of the carbonate chemistry of two tide pools on San Juan Island
Open ocean observations have shown that increasing levels of anthropogenically-derived atmospheric CO2 are causing acidification of the world’s oceans. Yet little is known about coastal acidification and very few studies have characterized the carbonate chemistry of coastal zones or intertidal rock pools where many calcifying ...
Variation of environmental forcings and the potential for changes in carbonate chemistry of the San Juan Archipelago
The carbonate chemistry of the San Juan Archipelago is extremely varied between regions of low to high tidal flushing. Salinity seems to be a driving parameter of the carbonate system through its effects on alkalinity. Freshwater from the Fraser River may control the environmental characteristics of water moving through the ...
A Tale of Two Tide Pools: Examining Carbonate Chemistry in the Intertidal
Characterization of physical conditions in tide pools is quite common in the scientific literature, but there is a marked paucity of information regarding the carbonate chemistry of these ecosystems; the majority of studies focus on temperature, salinity, and dissolved oxygen measurements. This lack of information is especially ...
THE TALE OF TWO TIDEPOOLS: EXAMINING CARBONATE CHEMISTRY IN THE INTERTIDAL
Tidepools are a prominent feature of the intertidal zone, housing a great diversity of both macroalgae and mobile animal components. Tidepool organisms are exposed to wide variations in temperature, salinity, and pH over the course of the low tide. As of yet, very few studies have quantified the changes in carbonate chemistry ...
Sources of Error in Carbonate Chemistry: What happens when Biology and Chemistry meet?
Two different experimental systems were used to evaluate sources of error in carbonate chemistry measurements at Friday Harbor Labs, WA. One system, set up in Laboratory 6, examined the effects of different filters and a UV sterilizer. The second system explored the carbon input from feeding live versus dead algae in the ...
Variation in Carbonate Chemistry throughout the San Juan Archipelago
Due to the dynamic nature of the water masses in the San Juan archipelago, the carbonate chemistry has not yet been well defined in space and time. For this short-term study during a neap to spring tidal cycle in mid July 2011, we analyzed water samples as far west as Kellett Bluff and as far east as East Sound for dissolved ...
