Deploying Buoys for Oyster Farm Research!

With the support of Cathy Cipolla and Gary Savoie, Fiona and Hongjie successfully deployed two buoys near the Wickford Oyster Farm to monitor the water chemistry, which may potentially impact oyster performance.

Thomas captivated the audience with his thesis presentation at Alaska Marine Science Symposium (AMSS2024): “Ocean acidification in the Pacific-Arctic Region: Bridging carbonate system observational gaps”. His study confirmed that faster sea ice loss is the speeding up the ocean acidification in the Artic regions.  Spotlight Moment: Thomas is ready to inspire the crowd with his presentation!

Abby, with the support of Georgia, delivered an talk on “Unraveling Natural Carbonate Variability in Narragansett Bay, RI Using Multiple High Temporal Resolution pH Time Series”. Their findings uncovers that biological processes are the dominated process shaping the pH levels in Narragansett Bay on a short-term scale.Snapshot: Abby is presenting the time series to audience.

Fiona shared the promising and limitation of Macroalgae Cultivation in mitigate ocean acidification. Her research offers a glimmer of hope, suggesting that macroalgae cultivation can only temporarily enhance local pH levels.In Action: Fiona is sharing her pioneering insights at AGU!

December 11, 2023

Olivia, in collaboration with Fiona, shared her SURFO project findings on “Harnessing Nature’s Buffer: Assessing Oyster Shell Dissolution for Ocean Acidification Mitigation and Ocean Alkalinity Enhancement”. Their 140-day incubation study reveals the potential of oyster shells in combatting ocean acidification and urging a re-think of oyster shell disposal laws.Inspiring Scene: Olivia is presenting this interesting talk at AGU.A Wang lab reunion at AGU2023.

A heartfelt appreciation goes to Kris Gomes, Andy Davies, and the generous NSF funding agency. Owing to their unwavering support, we’re thrilled to access real-time seapHOx data from Narragansett Bay. Keep an eye out, as there’s more sensor deployment lined up this Fall!

Our divers Katie (left) and Kris (right) poise and prepare to deploy the SeapHOx sensors.

Georgia outlines her approach to distinguishing the factors influencing pH.

Hearty congratulations to our SURFO student, Georgia Ahumada! Collaborating with her student mentor, Abby Baskind, Georgia delved into intricate pH data collected from January 2022 onwards from both the northern and southern regions of Narragansett Bay. Their rigorous analysis quantified the varying contributions of different pH drivers, revealing that biological production predominantly influences pH changes across diverse timescales, from daily to annually. Explore more about their findings at AGU2023!

Olivia elucidates the motivation behind her innovative summer research.

Hats off to another brilliant SURFO student, Olivia Rebernik! Under the expert guidance of her student mentor, Fiona Teevan-Kamhawi, Olivia embarked on an enlightening summer experiment, delving into the Oyster Shell Dissolution rate using authentic Narragansett Bay water. They observed significant shell dissolution across all seawater treatments. This research brings to light the substantial benefits of reintroducing oyster shells to coastal regions. To delve deeper, catch their detailed discussions at AGU2023!

Exciting developments! We’ve successfully recovered the second SAMICO2 from Greenwich Bay. An initial review of the SAMICO2 data paints an optimistic picture, although the most recent month shows signs of biofouling interference.

Hongjie is presenting the talk in session “Marginal sea biogeochemical cycling in the Anthropocene” in OCB 2023 summer workshop

June 13, 2023

Hongjie gave an invited talk at OCB 2023 summer workshop titled as “Abating marginal sea eutrophication, hypoxia and implications for nutrient management”.

June 12, 2023

Fiona’s poster became a big hit at the OCB 2023 poster session! The poster, based on over five months of close observation, presented the potential of kelp in mitigating ocean acidification at a local scale. Essentially, kelp can provide a more buffered pH environment – a form of shelter – to marine organisms. However, it was observed that the impacts quickly diminished after the kelp were harvested.

The weather has become more pleasant in Rhode Island, and the Kelp grew very fast because of the climbing water temperature. Here is one picture taken by Justin Sankey showing Hongjie and Fiona working on recalibrating the sensors in the Point Judith kelp Farm.

Congratulations to Hongjie Wang, Andrew Davis, Dave Ullman, and Jason Grear from EPA. Their proposal titled “ Drivers of ocean acidification in a temperate urbanized estuary undergoing nutrient loading reductions” is awarded by NSF-Chemical Oceanography (06/01/2023 ~05/31/2026). This project will leverage the existing water quality monitoring network, collect new data, and utilize a coastal biogeochemical model to quantify the variability of OA and the mechanisms driving its change in Narragansett Bay. Ph.D. student Abby Baskind from Wang lab will lead the integration of the OA module into the biogeochemical model. Through engagement with public and local shellfish growers, we will increase their awareness of OA and enhance their ability to site new aquaculture operations in the near and long term.

Big thanks to Dr. Kristofer Gomes, Ms. Ruby Dener and Emma, We have successfully retrieved the SeapHOx sensor after two months of deployment in Narragansett Bay! During this two-month deployment, the surface sensor captured fine-scale changes resulting from tidal mixing, freshwater input, and biological processes. Here is a screenshot showing the high-resolution pH drop from 7.8 to 7.5 after the precipitation in early November.
