Some Notes on Water Color in Keweenaw Bay (Lake Superior)

Journal of Great Lakes Research, 2004
Spectral subsurface irradiance reflectance—intrinsic water color—was derived from above-water radiance measurements using a hand-held spectroradiometer along a transect on Keweenaw Bay, Lake Superior. The reflectance spectra were typical of oligotrophic lacustrine waters. The reflectance peak wavelength shifted from 484 nm at stations farthest offshore

OPTICAL PROPERTIES AND COLOR OF LAKE TAHOE AND CRATER LAKE1

Limnology and Oceanography, 1973
Spectral irradiance has been measured as a function of depth in Crater Lake, Oregon, and Lake Tahoe, California. In Lake Tahoe, Secchi disk observations and submarine photometer measurements have been recorded year round since July 1967. Also, in Lake Tahoe, beam transmittance has been measured as a function of depth. From these data the radiant energy

Beyond the color: A structural insight to eosin-based lakes

Dyes and Pigments, 2017
Motivated by the fugitive and undisclosed nature of eosin-derived pigments as used by Vincent van Gogh, this paper presents the syntheses of monometallic and historical bimetallic eosin-based lakes and structural elucidation by MS, ATR-FTIR and NMR. Specifically two monometallic (Al, Pb) and several bimetallic lakes (on varying Al and Pb constituents ...

Interannual variation in the thermal structure of clear and colored lakes

Limnology and Oceanography, 2000
We used end‐of‐summer temperature profiles to examine the thermal structure of 86 small (<500 ha) lakes in Killarney Park, Ontario, Canada, during one cool (1997) and two extremely warm years (1998 and 1999). The main effect of the warm years, which had unusually high air temperatures during the spring, relative to the cool year was to create warmer

Ice Detection for Satellite Ocean Color Data Processing in the Great Lakes

IEEE Transactions on Geoscience and Remote Sensing, 2017
Satellite remote-sensing data are essential for monitoring and quantifying water properties in the Great Lakes, providing useful monitoring and management tools for understanding water optical, biological, and ecological processes and phenomena. However, during the winter season, large parts of the Great Lakes are often covered by ice, which can cause ...
