Color Reflectance

Data Request Form

About This Form

This form enables the retrieval of subsets of color reflectance data stored in the ocean drilling database. The data was acquired using a Minolta CM2002 camera.

Specify only those fields on which you wish to limit the query. For example, if you want to see information for one specific hole, you must fill-in the leg, site, and hole identifiers and leave the remaining fields blank.

Due to the size of the data warehouse, it may not be efficient to download the entire Color Reflectance dataset via the web. If this page does not meet your data request needs, please contact the Data Librarian.

Below is a brief sample of the data returned:

Outputting Raw Data

Setting the Output Raw Data? flag causes the raw reflectance data from the Minolta CM2002 to be displayed. 31 columns of reflectance values are displayed--one reflectance value per channel from 400-700nm. This spectrum is partitioned at 10nm intervals.
