Mapping chlorophyll-a in Lake Kivu with remote sensing methods - Zurich Open Repository and Archive


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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
