Short Biography

Michael received an A.A degree in Geography and an A.A. degree in Cartography  from Montgomery College, along with a bachelors degree from the University of Maryland in Geography in 1987. He started working at the USGS, Reston, Virginia facility in 1989 with the Geologic Division - the Branch of Atlantic Marine Geology (BAMG). Michael maintained GIS and technical support for the Coastal Marine Program, the Wetlands Program and the Global Warming Program offices located in Woods Hole, Mass., St. Petersburg, Florida and Reston, Va. In 1993, he joined the USGS Office of Water Information (OWI), maintaining GIS support, technical information, IT related duties, and the production of official USGS publications for the WRD offices of - Publications Assistance Unit (PAU), Customer Relations & Communications (CRC), Water Informaton Coordination Program (WICP), National Water-Quality Assessment Program (NAWQA) and Water Information Computer Application Support (WICAS).

Science and Technical Employee Development (STED) @ (Internal Access Only). The Scientific and Technical Employee Development (STED) function is to provide guidance and feedback on employee development and training within the Water Resources Division. The objective is to provide information on and give links to training options specifically for hydrologic data collectors and hydrologists looking for career paths and training opportunities within the hydrologic field - including Water Quality, Surface Water, Ground Water and Water Use disciplines.

USGS Environmental Affairs Program @ (Public Access). As a Federal agency with special expertise in the earth sciences, the U.S. Geological Survey (USGS) is required to evaluate, review, and prepare technical comments on environmental impact statements (EIS) and associated documents prepared by other Federal agencies. In addition, through its Environmental Affairs Program (EAP), the USGS has established policies to implement the National Environmental Policy Act (NEPA). [Link]

USGS WRD NSDI GIS Node @ (Public Access). Spatial Data Sets Available on the WRD NSDI Node. Operates, updates and maintains the Spatial Data Sets Available on the WRD NSDI Node ( in association with the National Spatial Data Infrastructure policy. These duties include ensuring that the metadata is validate, the maintainance all GIS datasets. checks that the correct dataset naming conventions and formats are utilized and verifies that all spatial data, file formats, schema, and associated GIS files follow the FGDC compliancy standards before installation; along with identifying problems for correction and resolution.

National Capital Area ARC/INFO Users Conference, January 9-10, 1992, Surficial Sediment Classification Maps Offshore Louisiana, Best Use of Arcplot, Overall Best Poster [Link]

National Capital Area ARC/INFO Users Conference 1993. Second Place. I compiled into digital form using Arc/info GIS software, the Robert H. Chabreck and Greg Linscombe vegetation type map of the Louisiana coastal marshes over a 10 year duration. Salt marshes, fresh marshes, brackish marshes and intermediate marshes were identified and areas, perimeters, and rates of change among the various marsh types were determined. [Link]

National Capital Area ARC/INFO Users Conference 1993. Best Project to Work On Award. Glaciological and coastal-change maps of the coastal regions of Antarctica at 1:1,000,000 and 1:500,000 scales. Generated and transformed maps into Lambert conformal projection with appropriate standard parallels of latitude for each map; longitudes were plotted and annotated every 15 minutes. The grid and graticules of projection were extended 4 degrees of longitude and 1 degree of latitude beyond the map boundary to ensure map accuracy and proper tiling of the map sheets, with the name located in upper right corner of each plot. Extracted various geographic data from other sources (maps, digial tapes, etc.) and transformed that data to Lambert Conformal projection. Digitized linear segments, glaciological features, geodetic control points, contours and other geographic information to the projected database. Transformed Landsat images into Lambert Conformal Conic Projection using the image integrator (Arc/info module) and merged all data together for the Antarctica database. [Link]
