Research Statement

I greatly enjoy my time spent working at sea. My at-sea experience includes coordination of at-sea science timelines, cruise logistics management, shipboard CTD and ADCP data processing, mooring instrumentation configuration and processing, and integration of satellite ice products with science operation plans. While I primarily sail with physical oceanography teams, I enjoy working with interdisciplinary groups and specialize in working in the Arctic environment.

My expertise in data processing and calibration focuses on (but is certainly not limited to!) shipboard and moored hydrographic data including measurements of ocean temperature, salinity, dissolved oxygen, and currents. My experience includes extensive work with post-calibration methods, UHDAS/CODAS data editing, technical documentation, and supporting research efforts within the physical oceanography department. I have a specific interest in developing best practices for hydrographic data collection methods specific to high-latitude environments.

Example technical and cruise reports

Example CTD processing reports

  • In June 2020, the AR45 cruise for the Overturning in the Subpolar North Atlantic Program took place during the unprecedented COVID-19 pandemic. As a safety measure, the science party was reduced in number resulting in the limited ability to analyze salinity samples while at sea. The following report summarizes CTD processing and calibration of 162 CTD casts spanning locations from the Greenland coast extending into the Labrador and Irminger Seas in light of limited sampling capabilities.
  • The AR30-06 cruise for the Overturning in the Subpolar North Atlantic Program took place during the late summer of 2018. The following report summarizes CTD processing and calibration of 296 CTD casts spanning locations from the Greenland coast extending into the Labrador and Irminger Seas.
  • The Distributed Biological Observatory – Northern Chukchi Integrated Study program focused data collection in the shallow waters (~40 m depth) of the Chukchi Sea. The following report documents methods used in data quality control measures in light of the uniquely shallow and strongly stratified waters encountered.
  • During the winter months of 2018, the Iceland Greenland Seas Project embarked on two month-long cruise legs in the Nordic Seas. Several CTD operational challenges were met in light of the extreme temperatures and sea states encountered. The following report summarizes challenges, solutions, lessons learned from the expedition, and impact on CTD data.
