The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

Title: |
Larkin Mill Dam Oblique photography of measured channel cross-sections from left and right bank monuments from 2008-06-09 to 2016-03-31 (NCEI Accession 0152485) |
Abstract: |
This dataset includes stream channel geometry and bed sediment grain size distribution data at the Parker River to evaluate physical habitat changes associated with the planned Larkin Mill Dam removal. In addition to evaluating channel response to dam removal, two years of pre-removal data collection (2008 and 2010) bracketed a large flood event that allowed us to investigate whether this small dam is an efficient sediment trap. Our analyses suggest that sediments readily move over the dam during storm events and other flows, and we hypothesize that, aside from a thin active surface layer where erosion and deposition regularly occurs, the small quantity of stored sediments is relatively stable. This archive package contains photographs in a PDF document. |
