Primary productivity data (growth rates) was obtained for Ecklonia radiata growing in nineteen sites within and just outside Marmion Lagoon. In addition, benthic water temperatures (C) were also collected at each of the sites along with light intensity data (LUX). There were three sample periods of approximately 30 days in December/January, May/June and October/November 2009. Nineteen sites were chosen for the trial. Five sites were selected in deeper water outside the lagoon while eight sites were selected across the mid lagoon. The mid lagoon sites were chosen so as to provide an indication of the growth rates of E. radiata under a wide variety of different light conditions but similar temperature regimes. Six inshore sites were also selected, three of which were in a sheltered position while three were from a more exposed sites. The density of E. radiata at each of the sites was calculated by counting all sporophytes >2 cm in three 1 m2 quadrates, haphazardly placed within an 8 m radius of the stake marking each site. Light and temperature measurements were logged for each site using a Hobo TM light and temperature logger set to log these parameters every 10 minutes.

This study was carried out at Davies Reef in the central Great Barrier Reef region, and measured for algal biomass and primary productivity and compared to surrounding epilithic algal communities. At Davies Reef the distribution and comparative cover of damselfish territories were examined in detail. Three automatic data-logging respirometers were deployed for 24 h in the field to measure productivity parameters - light (as irradiance, Li-cor), temperature and oxygen concentration at intervals of 1 to 255 min. Primary productivity was estimated from diel patterns in oxygen flux using data from: photosynthesis-irradiance relation (Ik, Icomp and alpha); rates of photosynthesis (P) and respiration (R); primary productivity expressed as the area1 gross (Pg) and net (Pna) rates and as the net turnover (Pnb) of community biomass (B, g C m-¹). These results were compared to the parameters: damselfish species (Plectroglyphididon lacrymatus, Stegastes apicalis, S.fasciolatus, S. nigricans); reef location; date; inside/outside fish territories. At Davies Reef two experiments examined damselfish territoriality impacts on algae in detail. Algal productivity inside and adjacent to the territories of 2 species was measured using square blocks (8 x 8 x 2 cm) of Porites which had been attached to the respective reef substrata for a period of 12 months prior. In the second experiment, coral blocks with established algal covering from non-territory substrata were caged with wire mesh to exclude all large grazers for 30 d, then the productivity of the increased algal biomass on these blocks was measured by respirometry, uncaged blocks were measured at the same time. The surface area of Acropora sp. branches was calculated. Algal biomass was determined by drying coral rock samples at 60°C and scraping the surface to a depth of 2 mm. Scrapings were ground, redried, and then analysed for total organic carbon. Four major substratum categories were surveyed: fish territories with dense mats of turf algae; closely-cropped filamentous and encrusting coralline algae; bare sand; organisms other than algae. Fourteen sites were established along each of three sections of Davies Reef (northern, central and southern): front reef slope at depths of 10 (#l) and 5 m (#2); reef crest (#3); reef flat at 20 (#4), 60 (#5), 80 (#6), 110 (#7) and 145 m (#8) behind the crest; reef flat at lagoon edge (#9, 190 m from the crest); lagoon slope at 5 m (#10) and 10 m (#11) depths; back reef flat (#12); and back reef slope at 5 m (#13) and 10 m (#14) depths. At each of these sites, a 100 m tape transect was surveyed perpendicular to the section lines and the length of intercept to the nearest 1 cm for each major substratum category and damselfish territory was recorded. The aims of this study were to: To quantify differences in reef epilithic algal community metabolism. To assess the significance of these in the context of total reef primary productivity. Epilithic algal communities include coralline algae, turf algae (filamentous forms and thick turfs), corallines mixed with short turf.

ATP3 Unified Field Study DataThe Algae Testbed Public-Private Partnership ATP3 was established with the goal of investigating open pond algae cultivation across different geographic climatic seasonal and operational conditions while setting the benchmark for quality data collection analysis and dissemination. Identical algae cultivation systems and data analysis methodologies were established at testbed sites across the continental United States and Hawaii. Within this framework the Unified Field Studies UFS were designed to characterize the cultivation of different algal strains during all 4 seasons across this testbed network. The dataset presented here is the complete curated climatic cultivation harvest and biomass composition data for each season at each site. These data enable others to do in-depth cultivation harvest techno-economic life cycle resource and predictive growth modeling analysis as well as develop crop protection strategies for the nascent algae industry.NREL Sub award Number DE-AC36-08-GO28308

HABSOS (Harmful Algal BloomS Observing System) is a data collection and distribution system for harmful algal bloom (HAB) information in the Gulf of America. The goal of HABSOS is to provide environmental managers, scientists, and the public with a data driven resource for HAB events. Cell counts and environmental information are combined into a single product and distributed using the HABSOS Mapping System. HABSOS strives to provide the most accurate picture of harmful algal bloom location and quantity by using the latest sample data available. This dataset contains data from Texas, Mississippi, Alabama, and Florida, as well as data along the Florida Shelf in the Gulf of America and along the eastern coast of Florida in the North Atlantic Ocean.
