Using self-organizing maps to determine observation threshold limit predictions in highly variant data Using self-organizing maps to determine observation threshold limit predictions in highly variant data
A significant data quality challenge for highly variant systems surrounds the limited ability to quantify operationally reasonable limits on the data elements being collected and provide reasonable threshold predictions. In many instances, the number of influences that drive a resulting value or operational range is too large to enable physical sampling for each influencer, or is too...

Varieties of submarine failure morphologies of seismically-induced landslides in Alaskan fjords Varieties of submarine failure morphologies of seismically-induced landslides in Alaskan fjords
The Great Alaska Earthquake of 1964 caused major damage and 43 deaths in the coastal communities of Seward and Valdez. Most of these losses were caused by tsunamis that occurred immediately after the earthquake and were most likely induced by local submarine landslides. Recent NOAA multibcam bathymetric surveys near Seward and Valdez provide detailed information about the morphology of...

Vertical variability in saturated zone hydrochemistry near Yucca Mountain, Nevada Vertical variability in saturated zone hydrochemistry near Yucca Mountain, Nevada
The differences in the saturated zone hydrochemistry with depth at borehole NC-EWDP-22PC reflect the addition of recharge along Fortymile Wash. The differences in water chemistry with depth at borehole NC-EWDP-19PB appear to indicate that other processes are involved. Water from the lower part of NC-EWDP-19PB possesses chemical characteristics that clearly indicate that it has undergone...

Vicarious calibration of GOES imager visible channel using the moon Vicarious calibration of GOES imager visible channel using the moon
In this paper, we study the feasibility of a method for vicarious calibration of the GOES Imager visible channel using the Moon. The measured Moon irradiance from 26 undipped moon imagers exhausted all the potential Moon appearances between July 1998 and December 2005, together with the seven scheduled Moon observation data obtained after November 2005, were compared with the USGS lunar...

Wave energy dissipation by intertidal sand waves on a mixed-sediment Beach Wave energy dissipation by intertidal sand waves on a mixed-sediment Beach
Within the surf zone, the energy expended by wave breaking is strongly influenced by nearshore bathymetry, which is often linked to the character and abundance of local sediments. Based upon a continuous, two year record of Argus Beach Monitoring System (ABMS) data on the north shore of Kachemak Bay in southcentral Alaska, we model the enhancement of wave energy dissipation by the...

Habitat and fish population in the deep-sea Oculina coral ecosystem of the western Atlantic Habitat and fish population in the deep-sea Oculina coral ecosystem of the western Atlantic
In this paper, we describe results from mapping studies conducted in 2001 and improvements to reef fish populations that have occurred in the last few years. We find that less than 10% of the area contains intact Oculina coral thickets, which we continue to attribute primarily to trawling. In addition, we find increased grouper density and male abundance inside the protected area...
