Areas of Specialization

Research

Alfred Hanson's research interests in chemical/biological oceanography are the distribution, speciation and biogeochemical cycling of trace elements, the marine photochemistry of trace metals and organic substances, factors controlling the bioavailability and toxicity of trace metals, the photobiological and photochemical effects of UV radiation in marine waters, biogeochemical processes associated with suboxic coastal waters, influence of small-scale and episodic processes on nutrient cycling and biogeochemical dynamics, and the development of submersible chemical oceanographic instrumentation.

Teaching

Marine Research Scientists are primarily involved in funded research and do not generally teach classes. In some cases Marine Research Scientists advise graduate students on their thesis research. I have recenly submitted an application for the open position of Dean of the GSO. If you are interested in seeing the cover letter and CV that was submitted to the Dean Search Committee on Nov. 22,2011, then go to this link: http://www.subchem.com/Dean GSO.htm.

Outreach

Alfred Hanson is actively involved in the applied arena of coastal ocean observations, particularly with the Northeastern Regional Association for Coastal Ocean Observing Systems (NERACOOS), which is primarily funded by NOAA.. He participates as a member of the Board of Directors and of the Strategic Planning and Implementation Team for NERACOOS, and is also Chairman of the North East Academic Consortium (NEAC), which advises NERACOOS. Alfred Hanson is the principal investigator of a NERACOOS nutient monitoring project. URI-GSO has been funded by NERACOOS/NOAA to establish and operate a nutrient sensing facility in the Center for Marine and Atmospheric Chemistry, located on the Bay campus. URI and NERACOOS has a long-term goal of obtaining and analyzing in situ, time-series measurements of nutrient concentrations by deploying commercially available sensors at key NERACOOS locations and time periods. http://www.neracoos.org/projects/nutrients.html . The plan is that the URI Nutrient Sensing Laboratory will ultimately oversee the care-taking, analytical calibration, operation, deployment and data processing for in situ nutrient sensors deployed on moorings, and other observation platforms throughout the Northeast. http://www.subchem.com/neracoos.htm
