Identifying phytoplankton assemblages with hierarchical cluster analysis: The clustering of the hyperspectral phytoplankton absorption coefficients generates a cluster tree

چکیده
Phytoplankton pigments, group composition and absorption coefficients: The following diagnostic pigments were used to identify seven phytoplankton groups: fucoxanthin (Fuco), peridinin (Peri), alloxanthin (Allo), 19 ́-hexanoyloxyfucoxanthin (19HF), 19 ́-butanoyloxyfucoxanthin (19BF), zeaxanthin (Zea), and total chlorophyll-b (TChlb, i.e. the sum of monovinylchl-b, chl-b, and divinylchl-b (div-b)). According to Hirata et al. (2011) the weighted relationships of these diagnostic pigments (DPw) were calculated by multiple regression analysis as follows:

Study of phytoplankton community in coastal waters of Hormozgan province, Qeshm and Leangeh Islands
The study of spatial and temporal variability of distribution of phytoplankton communities in Northern part of the Persian Gulf (Qeshm andLengeh Islands) was studied. In this study, five groups (47 genera) of phytoplankton include Bacillariophyceae, Dinophyceae, Cyanophyceae, Crysophyceae and Euglenophyceae were identified. The results showed that Diatoms group (79.6 %) and Rhizosolenia genus (...

The emergence of hyperspectral optical satellite sensors for ocean observation provides potential for more detailed information from aquatic ecosystems. The German hyperspectral satellite mission EnMAP (enmap.org) currently in the production phase is supported by a project to explore the capability of using EnMAP data and other future hyperspectral data from space. One task is to identify phyto...

متن کاملGraph Clustering by Hierarchical Singular Value Decomposition with Selectable Range for Number of Clusters Members
Graphs have so many applications in real world problems. When we deal with huge volume of data, analyzing data is difficult or sometimes impossible. In big data problems, clustering data is a useful tool for data analysis. Singular value decomposition(SVD) is one of the best algorithms for clustering graph but we do not have any choice to select the number of clusters and the number of members ...
متن کاملPhytoplankton Group Identification Using Simulated and In situ Hyperspectral Remote Sensing Reflectance
In the present study we investigate the bio-geo-optical boundaries for the possibility to identify dominant phytoplankton groups from hyperspectral ocean color data. A large dataset of simulated remote sensing reflectance spectra, Rrs(λ), was used. The simulation was based on measured inherent optical properties of natural water and measurements of five phytoplankton light absorption spectra re...
