Phytoplankton_SES Data

Seal ID is a matlab character array of 227,293 observations (rows) showing the seal ID for each observation. SES observation dates.mat is a character array of 227,293 observations showing the date of each observation. SeaElephantsDataPigmSatClass.mat is a numeric array of 227,293 observations by 24 columns, column 1 is the observation id, column 2 is a naming id, column 3 is the latitude, 4 is the longitude, 5 refers to , 6 is the PrCA, 7 is the normalized PrCA based on the variance of each individual, 8 to 17 are the 10 phytoplankton pigments :total Chla, Divynil-Chla (DVChla), Chlb, Divynil-Chlb (DVChlb), 19'Hexfucoxanthin (19HF), 19'Butfucoxanthin (19BF), Fucoxanthin (Fuco), Peridinin (Perid), Alloxanthin (Allo), and Zeaxanthin (Zea), 18 is the satellite Chla, 19 to 22 are the Rrs at the 4 wacelengths (412,443,490,555), 23 is the sea surface temperature (SST), and 24 is the class for the same pixel of the observation based on the date, latitude, and longitude. SOM_Pigment_Training.m is the matlab script containing the code used to train the Self-Organizing Map. SOM-Toolbox-master.zip contains all the necessary functions and is a prerequisite software library (SOM Toolbox 2.0) for Matlab, implementing the self-organizing map algorithm, Copyright (C) 1999 by Esa Alhoniemi, Johan Himberg, Jukka Parviainen, and Juha Vesanto and accessible at https://github.com/ilarinieminen/SOM-Toolbox.海豹标识（Seal ID）是一个包含227293条观测记录（行）的Matlab字符数组，用以存储每条观测对应的海豹标识。 SES observation dates.mat 是一个包含227293条观测记录的字符数组，用于存储每条观测的观测日期。 SeaElephantsDataPigmSatClass.mat 是一个维度为227293条观测记录×24列的数值数组：第1列为观测ID，第2列为命名ID，第3列为纬度，第4列为经度，第5列指代内容原文缺失，第6列为PrCA，第7列为基于个体方差归一化后的PrCA；第8至17列为10种浮游植物色素：总叶绿素a（total Chla）、二乙烯基叶绿素a（Divynil-Chla, DVChla）、叶绿素b（Chlb）、二乙烯基叶绿素b（Divynil-Chlb, DVChlb）、19'己烯基岩藻黄素（19'Hexfucoxanthin, 19HF）、19'丁烯基岩藻黄素（19'Butfucoxanthin, 19BF）、岩藻黄素（Fucoxanthin, Fuco）、多甲藻黄素（Peridinin, Perid）、别藻黄素（Alloxanthin, Allo）以及玉米黄质（Zeaxanthin, Zea）；第18列为卫星反演叶绿素a（satellite Chla）；第19至22列为4个波长（412、443、490、555）下的遥感反射率（Remote Sensing Reflectance, Rrs）；第23列为海表温度（sea surface temperature, SST）；第24列为基于观测日期、纬度与经度划分的观测对应像素类别。 SOM_Pigment_Training.m 是用于训练自组织映射（Self-Organizing Map, SOM）的Matlab脚本文件，内含训练代码。 SOM-Toolbox-master.zip 包含所有必要的功能函数，是Matlab环境下运行自组织映射算法所需的前置软件库（SOM Toolbox 2.0）。该工具库由Esa Alhoniemi、Johan Himberg、Jukka Parviainen与Juha Vesanto持有1999年版权，可通过https://github.com/ilarinieminen/SOM-Toolbox获取。
