Supplemental Data: Effects Of Physical Mixing On The Attenuation Of Polycyclic Aromatic Hydrocarbons In Estuarine Sediments., Krisa M. Arzayus, Rebecca M. Dickhut, Elizabeth A. Canuel

Reports

To examine the role of physical disturbance on the long-term preservation of polycyclic aromatic hydrocarbons (PAHs) in sediments, cores were collected from two sites removed from point sources of PAHs and representing contrasting seabed mixing regimes. Although SPAH concentrations in sediments over the past 50 years were not significantly different between the two sites, several PAH isomer ratios were significantly different (p

Surface Observations, Ground Truth And Data : Nasa-Usgs Mission 144 : Chesapeake Bay Region, Sept. 22-30, 1970, Maynard M. Nichols

Reports

Surface observations of coastal waters and "ground. truth" data were obtained to aid interpretation and analyses of overflight photography and imagery. Among the broad objectives of the mission was to investigate the potential of high-altitude, multispectral photography as a tool for the improved planning necessary to cope with multidisciplinary problems within the coastal zone, specifically with regard to:

1. The inventory and evaluation of the central Atlantic coastal area natural resources;

2. The assessment of human and natural degradation of these resources;

3. The feasibility of monitoring resource allocation and management, including land use categories and the impact of urbanization …
