    Coefficients of the Global Space-based Inter-Calibration System (GSICS) Correction for the infrared channels of a GEOstationary imager using a LEO hyperspectral reference instrument

  • Categories  

    EMEP station in the central part of Finland with forest, swamps, small fields and medium size lakes around. The area is free of large local and regional pollution sources. A main road lies 5 km to SW. The nearest population center is Ahtari, 7 km to SW, with 7000 inhabitants butlarger towns are over 70 km away.

    Temperature data from the TOGA/WOCE transect PX34 across the Tasman Sea has been collected since 1991 and are ongoing. The transect is repeated approximately 4 times a year, with profiles obtained approximately every 10-50 Km. The data are obtained from XBTs (expendable bathythermographs) deployed via merchant vessels, and are managed by the Joint Australian Facility for Ocean Observing Systems (JAFOOS), a collaborative venture between CSIRO Marine Research and the Bureau of Meteorology Research Centre (BMRC).

    About 60 km northeast of Tokyo. The population of Tsukuba is 165,000, with vegetated, rice producing and urban areas located in (286.50 km2) and around the city.

    These data sets include Salinity, Carbon, Alkalinity, Oxygent and Nutrients (Silicate, Ammonium, Nitrite/Nitrate, Phosphate) analysed from samples collected as part of the Integrated Marine Observing Systems (IMOS) National Mooring Network -National Reference Station (NRS) field sampling. Nine Sites are included in the IMOS NRS field sampling stations. Maria Island (TAS), Kangaroo Island (SA), Esperance (WA), Rottnest Island (WA), Ningaloo (WA), Darwin (NT), Yongala (QLD), North Stradbroke Island (QLD) and Port Hacking 100 (NSW). Sampling at these sites is conducted by several members of IMOS NRS Biogeochemical project. Sampling at the sites began between 29/9/2008 and 8/11/2010 and is currently ongoing for 7 sites. Sampling ceased at Ningaloo and Esperance (WA) sites in Aug/Sept 2013. Sampling is conducted monthly (Esperance and Ningaloo were 3 monthly) off small vessels. Depths sampled range from surface to 105 metres depending on the site. Depths are usually sampled at 10 metre intervals. Details including information on station locations, depths sampled and sample types collected are shown in the PDF link below extracted from the IMOS NRS NATIONAL REFERENCE STATIONS BIOGEOCHEMICAL OPERATIONS - A PRACTICAL HANDBOOK, Version 2.2 July 2012. A link to the full handbook is also provided which includes full details of the sampling regime and analyses. Historical data collected as part of CSIRO Coastal Monitoring program is available for three of the National Reference Station sites: Maria Island Coastal Station Data 1944-2008, Port Hacking 100m Coastal Station Data 1953-2010 and Rottnest Island Coastal Station Data 1951-2009. The links to the metadata and access for these data is provided below. Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource. Data is freely available through the AODN portal: https://portal.aodn.org.au.

    The station is roughly 17 km north of the small town Bukittinggi and around 120 km north of Padang which the capital of the province West Sumatra. The remote station Bukit Kototabang (which means Bukit=Hills) is situated in the equatorial zone on the ridge of a high Barisan plateau at an altitude of 864.5 m a.s.l., and 40 km off the western coastline. The prevailing winds are blowing either from south-south-east (December to May) or from north-north-west (May to October). The temperature varies from 16 to 25 °C with only slight annual variation and the relative humidity is usually higher than 80%, and the annual precipitation is >3000 mm. The facilities at the site consist of a large one-story building, which provides excellent space for offices, meeting room and laboratories. On the 300 m3 flat roof, the air inlet and several radiation and meteorological equipment are mounted. The station is reached over a small access road which is closed to the public and is a few kilometres off the westerly main road (moderate traffic) between Padang and Medan. The vegetation in the surrounding area (30 km) consists mainly of tropical forest.

    This dataset comprises the zooplankton abundance estimates of a broader sampling program carried out by the Plankton National Reference Station within the Integrated Marine Observing system. Regular monthly zooplankton samples are undertaken at the stations as part of a larger water sampling program by the Australian National Reference Stations. In total nine stations are sampled regularly around the Australian coastline. Sampling is conducted monthly (Esperance and Ningaloo 3 monthly) off small vessels at each of the nine reference stations. The sampling is conducted using a drop net (as per the design of Heron) which has a 60 cm diameter, 100 micron mesh and is weighted to fall at 1 m/s. The net is designed to pull closed at the end of its fall so that it samples on the way down and does not sample on the way up. The depth of the sample varies at each station. 3 zooplankton samples are taken each month. 2 are fixed in formalin and will be analysed as described below. The unfixed sample is concentrated and frozen (-80oC)and will be used for molecular analysis in the future. The Port Hacking 4 (PH4) samples (2002 - Jan 2009) were sampled using a smaller net, 20 cm diameter, which sampled on the way up and down. The PH4 site is very close to the Port Hacking national reference station (PHB) where samples are now taken to build up and enhance the time series. The plankton ecology lab (based in Queensland) will analyse the samples collected for: 1. Community composition (Taxon/m3) 2. Biomass (dry weight in mg/m3) 3. Size spectrum analysis using zooscan (in progress) Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource. Data is available freely via the AODN portal: https://portal.aodn.org.au. As the taxonomic resolution of the data has changed over time, due to continual training, it is important that users refer to the change log tables included in your data download. These will provide information on the validity of the taxa, from what date we have been identifing certain taxa etc. Classification fields may be blank depending on the level to which that taxa has been identified, i.e. if only identified to family, genus and species will be blank.

    The overall aim of this project was to determine the geomorphological and sedimentary characteristics (biological and physical) of the Ningaloo Reef and shelf, and to identify evolutionary characteristics relevant to the maintenance of marine biodiversity. This included characterising reef growth history, coastal and seabed geomorphology, surficial sediment facies and their influence on the distribution of benthic habitats. This research presents an interdisciplinary study that provides an important baseline for future habitat mapping, biodiversity assessments, spatial planning, and fisheries management. The characterisation and mapping of benthic habitats based on physical parameters is central for the ongoing monitoring, management and conservation of the NMP’s inshore and offshore resources, particularly during a time of increasing anthropogenic and environmental pressures.

    This dataset comprises the phytoplankton abundance and biovolume estimates of a broader sampling program carried out by the Plankton National Reference Station within the Integrated Marine Observing system. Regular monthly phytoplankton samples are undertaken at the stations as part of a larger water sampling program by the Australian National Reference Stations. In total nine stations are sampled regularly around the Australian coastline. Sampling is conducted monthly (Esperance and Ningaloo 3 monthly) off small vessels at each of the nine reference stations. The sampling is an integrated water sample collected with niskin bottles at 10m depth intervals and preserved in lugols solution. The depth of the sample varies at each station. The plankton ecology lab (based in Queensland) will analyse the samples collected for: 1. Community composition / abundance (cells/l) 2. Biovolume (um3/L). Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource.
