  • Abstract: Wave buoys were deployed in Carr Creek and at the mouth of the Severn River in the Chesapeake Bay to collect wave data (significant wave height, wave period, wave direction) in February-March 2022. These data were compared to weather data to determine and contrast the wintertime wave fields at these two geomorphologically-unique coastal locations under different meteorological forcing conditions.

Poster #264. Early Spring Conditions in Santee Basin and the Potential for Blooms of Harmful Algal Species

  • Researchers: MIDN 1/C Morgan Lang, 1/C Stella Blackwell, 1/C Antonio Orama, 1/C Sarah Ryser

  • Abstract: Water level data obtained from the NOAA Annapolis Tide Gauge on the Severn River, a HOBO MX Water Level Logger deployed in Ego Alley, and a Campbell Scientific CS475A-L Radar Water Level Sensor deployed in Spa Creek will be compared and statistically analyzed for differences. Additionally, wind forcing, precipitation, and temperature will be explored to better understand the drivers of the observed differences and trends.

Sediment traps were deployed along with a bottom-moored laser particle size analyzer to quantify wintertime sedimentation rates. Results were compiled to make initial assessment as to the suitability of the Eaglenest Point Oyster Reef site in Round Bay as a potential restoration site.

Poster #268.  Does Intraseasonal Meteorological Variability Modulate Water-Levels along the U.S. East Coast?

  • Researchers: MIDN 1/C Steven Shen
  • Advisor(s):  Prof. Gina Henderson, Instr. Alexander R. Davies
  • Abstract: Nuisance flooding is increasingly threatening the viability of coastal communities along the U.S. East Coast. In this study, we investigate the relationship between intraseasonal meteorological forcing and water level variability at three locations in the mid-Atlantic region. Preliminary results indicate that specific atmospheric patterns support persistent onshore winds and may play a key role in modulating water levels.

Poster #269.  Connecting Antarctic max-Temperature Anomalies and the Madden Julian Oscillation

  • Researchers: MIDN 1/C Sara Vianco
  • Advisor(s):  Prof. Gina Henderson, LT Matthew Lafleur
  • Project Sponsor: U.S. National Science Foundation (NSF)
  • Abstract: Following the occurrence of extreme melt events in Antarctica, this study relied on the Real time Multivariate MJO Index, the ERA-5 dataset, and GSOD station data to analyze the occurrence of max temperature anomalies during the 8 active MJO phases. We relied on MATLAB (R2021a) to process and visualize the data, and to infer whether or not the teleconnection between the MJO and the Antarctic atmosphere influenced patterns of these anomalies.

Poster #291.  Optical Tracking of a Chemical Plume in a Shallow Water Estuarine System Using a Custom ASV 

  • Researchers: MIDN 1/C Megan LaMendola
  • Advisor(s):  Assoc. Prof. Joseph P. Smith, Mr. Benjamin Hickman

  • Abstract: This study will demonstrate the capability of tracing the optical signature of chemical plumes using a custom-built autonomous surface vehicle (ASV) in Carr Creek, a shallow sub-tributary of the Severn River in Chesapeake Bay. The precited dispersion and transport of a simulated input of a waterborne chemical hazard will be compared with the actual dispersion of plumes from live releases of inert chemical proxy agents with known optical properties (dye release) as measured by the ASV.

Poster #292.  Variability in Wintertime Microplastic Concentrations and Particle Counts in Annapolis Harbor

  • Researchers: MIDN 1/C Gustel Bamanabio, 1/C Brycen Groess, 1/C Andrea Martinez, 1/C Alexandra Schofield
  • Advisor(s):  Instr. Brianna Tracy, Assoc. Prof. Joseph P. Smith
  • Project Sponsor: Volgenau Family
  • Abstract: The goal of this study is to quantify the concentration of microplastics in the Annapolis Harbor area through both gross weight and particle counts of the collected plastics. These samples will provide baseline winter data on microplastics within the Harbor area and insight into the reproducibility of concurrent microplastic transect collections. The data will also be compared to the results of microplastics data collected in previous years.

Poster #293.  Tracing a Wastewater Effluent Plume in Carr Creek

  • Researchers: MIDN 1/C Tanner Gage, 1/C Meghan Sculli, 1/C Phillip Lee, 1/C Sydney Dinan

This fingerprint was used to assess and quantify the dispersion and extent of the NSAA AWWTP effluent plume under different environmental conditions.

Poster #294.  Humanitarian Assistance through Remote Sensing for Cyclone Gati in Somalia

  • Researchers: MIDN 1/C Elizabeth Twohig
  • Advisor(s):  Prof. Peter Guth
  • Abstract: Through high resolution satellite images, humanitarian assistance can be planned for similar countries afflicted from natural disasters.

Poster #295.  Remote Sensing Analysis of Kilauea

  • Researchers: MIDN 1/C Kiersten Honig
  • Advisor(s):  Prof. Peter Guth
  • Abstract: Using satellite imagery to analyze the changing features of one of the world's most active volcanoes. Kilauea is located on the Big island and has erupted nearly continuously for over 30 years. The consistent eruptions poses the question to determine how much the landscape has changed over the years and how it can be viewed through satellite imagery.

Poster #296.  A Testing Unit for the Optimization of Chlorination to Control Biofouling in Shipboard Systems

  • Researchers: MIDN 1/C Jennifer Chatwell
  • Advisor(s):  Assoc. Prof. joseph P. Smith, Mr. Benjamin Hickman

  • Abstract: A testing unit was employed to optimize chlorination used to reduce or control biofouling in submarine seawater cooling systems at Pearl Harbor Naval Shipyard (PHNSY). Results were compared to those for U.S. Navy platforms at PHNSY. Results show that sodium thiosulfate is a safe and effective alternative dechlorination agent to sodium metabisulfite that will enable PHNSY and the U.S. Navy to increase efficiency in controlling biofouling in submarine seawater cooling systems.

Poster #297. Understanding the Impact of Artificial Islands on Heat Flux in the South China Sea

  • Researcher: MIDN 1/C Joseph Colley
  • Advisor(s):  Assoc. Prof. Andrew Muller
  • Project Sponsors: U.S. National Geospatial-Intelligence Agency (NGA)
  • Abstract: The full environmental effects of the construction of artificial islands in the South China Sea by the PRC is not yet known. This project uses satellite derived current, temperature and salinity products to calculate surface heat flux in the Spratley Islands. Heat transport is calculated for selected locations and subjected to wavelet analysis to identify any coherence with oscillations such as ENSO and MJO and to identify regime changes following the construction of artificial islands.

Poster #298. Characterization of the Summertime Soundscape of a Pristine Oyster Reef in the Tred Avon River (Maryland, USA)

  • Researcher: MIDN 1/C Benjamin Hilliard
  • Advisor(s):  Prof. Cecily Steppe 
  • Abstract: Analyzing soundscapes can provide a less intrusive way to assess habitat dynamics than traditional field sampling methods. In this study we deployed a hydrophone on a pristine oyster (Crassostrea virginica) reef in the Tred Avon River (Maryland) to characterize the summertime soundscape. The relative frequency of anthropogenic, biological, and physical sounds were compared among time of day, and weekdays vs weekends to better understand stresses that may affect reef biota.
