Mapping chlorophyll-a in Lake Kivu with remote sensing methods


Kneubühler, Mathias; Frank, Toni; Kellenberger, Tobias; Pasche, Natacha; Schmid, Martin (2007). Mapping chlorophyll-a in Lake Kivu with remote sensing methods. In: Envisat Symposium 2007, Montreux (CH), 23 April 2007 - 27 April 2007.

Abstract

A multitemporal assessment of chlorophyll-a distribution using MERIS/ENVISAT FR data from 2003 through 2005 shows increased chlorophyll concentrations correlated to high algae bloom during the dry season from July to September. Intra- and interannual distribution patterns were investigated using spectral band ratio approaches. Maximum chlorophyll-a concentrations in Lake Kivu were found along the lake’s shore line, the southern basin, Bukavu Bay and Kabuno Bay. Regional and temporal variations are lowest in the lake’s central northern basin. Increased knowledge on the lake’s regional and temporal chlorophyll-a distribution may help for an improved description of the main features of nutrient cycling.
