Integrated dataset for red tide (Karenia brevis bloom) patterns on the west Florida shelf

This dataset contains integrated red tide (Karenia brevis harmful algal blooms) maps for the West Florida Shelf (24N – 31N, 87W – 81W) every month between 2003 and 2019. The integration is over in situ water sample analysis (which provides K. brevis cell concentration) and satellite data (which provides more frequent and spatial coverage than in situ data) using a practical approach. In situ cell counts data were obtained from a database maintained by the Florida Fish & Wildlife Conservation Commission (https://myfwc.com/research/redtide/monitoring/database/), and satellite data were collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Aqua satellite, available through NASA’s OB.DAAC (https://oceancolor.gsfc.nasa.gov). They were integrated to generate monthly maps of K. brevis bloom spatial extent and frequency.
Specifically, the maps are expressed as bloom occurrence frequency (BOF) and bloom intensity (BI). The boundary of bloom locations represents the bloom footprint. Both maps are in imagery format (color coded in png files, MODIS_KB_bloom_WFS_images.zip) and binary format (floating point Geotiff files, MODIS_KB_bloom_WFS_binary.zip).

本数据集汇集了西佛罗里达大陆架（24N – 31N，87W – 81W）自2003年至2019年每月的整合赤潮（ Karenia brevis 有害藻华）分布图。整合过程基于实际方法，结合了现场水样分析（提供 K. brevis 细胞浓度）和卫星数据（相较于现场数据，提供更频繁的更新和更广泛的覆盖范围）。现场细胞计数数据来源于佛罗里达鱼类与野生动物保护委员会维护的数据库（https://myfwc.com/research/redtide/monitoring/database/），而卫星数据则由搭载在 Aqua 卫星上的中分辨率成像光谱仪（MODIS）收集，可通过美国国家航空航天局海洋颜色数据中心（OB.DAAC）获取（https://oceancolor.gsfc.nasa.gov）。这些数据被整合以生成每月的 K. brevis 赤潮空间分布范围和频率图。具体而言，地图以赤潮发生频率（BOF）和赤潮强度（BI）来表示，赤潮位置的边界即为赤潮足迹。两种地图均以图像格式（png 文件中的彩色编码）和二进制格式（浮点 Geotiff 文件）呈现。
