<p><em>Sample Collection:</em></p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Four surveys were conducted of both the Pleasant and St. John estuaries, in May and October 2018, and again in May and October 2019 in order to assess potential differences in estuary conditions between spring and fall seasons. Estuary samples were collected during single-day surveys on small vessels in each system, departing from Addison Maine for Pleasant estuary surveys and from St. John, New Brunswick, for St. John surveys. Estuary water was continuously pumped to an underway measurement system, which recorded location, salinity(Seabird SBE-45), water temperature (Seabird SBE-45), and the partial pressure of carbon dioxide (pCO<sub>2</sub>) among other parameters. Surveys were started on the incoming tide and lasted through high tide and into the ebb tide. At intervals determined from the underway salinity, surface water was captured for discrete sample collection. During the October 2017 and May 2018 surveys a Niskin bottle was lowered overboard by hand; during the later surveys a 10-liter high-density polyethylene (HDPE) carboy was rinsed and filled from the outflow of the underway system, then tightly capped until samples were drawn from a spout at the bottom of the carboy. River endmember samples were collected from above the final downstream dam on each river. For the Pleasant, this dam formed a physical tidal barrier, and the transition from river to estuary was immediate. For the St. John the closest site was in Fredericton New Brunswick, a location over 120 km from the estuary mouth along the river’s course. For both endmember sites, a plastic bucket was lowered from the center of a bridge over the river, rinsed three times with river water, and samples were collected as described above. The temperature and conductivity of samples were measured directly from the bucket with a handheld meter (YSI, Yellow Springs, Ohio).</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Water from the Niskin or carboy was transferred without bubbling into individual, previously-flushed borosilicate glass BOD bottles: 500 mL for alkalinity and pH<sub>T</sub> analyses, and 300 mL for inorganic carbon (DIC) analysis. All bottles had greased stoppers and positive closure mechanisms, were filled to leave less than 1% headspace in the bottle, and were preserved with saturated mercuric chloride solution. Samples for silicate and phosphate analysis were filtered using a plastic syringe and 0.2 µm cartridge filter into acid-washed and previously-rinsed 50 mL HDPE vials and preserved with chloroform. Samples for DOC were filtered as was done for the nutrients into acid-washed and previously-rinsed 30 mL HDPE bottles. All samples were immediately placed on ice. Alkalinity, pH, and DIC samples were refrigerated until analysis; nutrient and DOC samples were frozen until analysis.<br />

Collaborative Research: Organic Alkalinity: Impacts of the [OTHER] Alkalinity on Estuary and Coastal Ocean Chemistry
<p>NSF Award Abstact:</p>
<p>Estuaries are bodies of water formed where rivers meet the ocean, and are important ecosystems that provide protected environments and abundant food for fish and shellfish to reproduce. Many estuary systems are under pressure by changing atmospheric and oceanic conditions, as well as impacts on the rivers that empty into them. Scientists from the University of New Hampshire and the University of South Florida propose that the total alkalinity of some coastal systems, influenced by river runoff, may contain a large fraction of organic acids that have been previously ignored and may play a role in the acid-base chemistry of the estuary. This project would focus on understanding the organic and inorganic acid-base chemistry in estuaries. The project will support a PhD student and several undergraduate students, as well as high school interns from minority communities, broadening participation in the ocean sciences. Also, the monitoring and outreach capacity of a regional wild fishery conservation group will be enhanced, allowing the public to be more fully informed on the effect of ongoing estuarine changes on fisheries.</p>
<p>This project will be a comparison study of two estuary-plume systems to examine the exact buffering impact of organic alkalinity on the acid-base properties of coastal systems. The Pleasant (Maine) and St. John (Canada) estuaries represent extremes of river acid-base systems, where the Pleasant is comprised mostly of organic alkalinity and the St. John has a small organic alkalinity fraction. It is hypothesized by these scientists that some coastal regions may experience organic alkalinity as the dominant alkalinity factor in the total alkalinity distribution. This would mean that organic alkalinity would be the dominant factor affecting system pH, pCO2 (partial pressure of carbon dioxide), and the saturation index of aragonite. By doing this river endmember study into organic alkalinity of these two systems, these scientists will provide the tools for the entire oceanographic community to assess the buffering capability of organic alkalinity in other coastal systems and how the systems are likely to respond to acidification.</p>
