Grazing experiments were conducted for the zooplankton Artemia franciscana on three of its most common Great Salt Lake (Utah: USA) phytoplankton species (> 80–90% of phytoplankton biovolume: a chlorophyte, Dunaliella viridis ; a cyanobacterium, Euhalothece sp., and a bacillariophyte, the pennate diatom Nitzschia epithemioides ). For each Artemia developmental stage (nauplii, juveniles and adults), grazing rates (same phytoplan...
Hypersaline Great Salt Lake’s (GSL: Utah, USA) pelagic food web is dominated by the herbivore, Artemia franciscana . Artemia demographic responses (survival, developmental transition, and reproduction) to GSL salinities, temperatures, common phytoplankton and yeast, and food levels were examined by factorial experiment. Survival across developmental stages was best at 90 ppt salinity, and decreased as temperature increased. Tr...
Coastal waters require monitoring of chlorophyll-a concentration (Chl-a) in a wide range of Chl-a from a few mg/m 3 to hundreds of mg/m 3 , which is of interest to the fisheries industry, evaluation of climate change effects, ecological modeling and detection of Harmful Algal Blooms (HABs). Monitoring can be carried out from the Visible Infrared Imaging Radiometer Suite (VIIRS) and Ocean and Land Colour Instrument (OLCI) Ocean...
This manuscript describes methods for evaluating the efficacy of five satellite-based Chlorophyll-a algorithms in Chesapeake Bay, spanning three separate sensors: Ocean Land Color Imager (OLCI), Visible Infrared Imaging Radiometer Suite (VIIRS), and MODerate Resolution Imaging Spectroradiometer (MODIS). The algorithms were compared using in situ Chlorophyll-a measurements from 38 separate stations, provided through the Chesape...
Characterizing a cyanobacterial bloom in Western Lake Erie using satellite imagery and meteorological dataNARA Subscribed
The distribution and intensity of a bloom of the toxic cyanobacterium, Microcystis aeruginosa , in western Lake Erie was characterized using a combination of satellite ocean‐color imagery, field data, and meteorological observations. The bloom was first identified by satellite on 14 August 2008 and persisted for > 2 months. The distribution and intensity of the bloom was estimated using a satellite algorithm that is sensitive...
