In oceanography, a front is a boundary between two distinct water masses. The water masses are defined by moving in different directions. The water masses on either side of a front may also have different temperatures, salinities, or densities, along with differences in other oceanographic markers.
This image represents the number of times a front has been detected in 166 monthly Sea Surface Temperature datasets.
Data is based on MODIS images aboard NASA Terra and Aqua satellites. The Canny operator algorithm was used in determining edges in the data.
This maps shows the geomorphic features of the seafloor in Solomon Islands EEZ. Conservation International, GRID-Arendal and Geoscience Australia recently collaborated to produce a map of the global distribution of seafloor geomorphic features. The map represents and important contribution towards the understanding of the distribution of blue habitats.
A map showing hydrothermal vents in Solomon Islands EEZ. The map was created by MACBIO as resource for the workshop on bioregions in Feb 2018. Data is based on InterRidge Vents Database.
Map showing a classification of seamounts in Solomon Islands EEZ. Classification is based on Blue Habitats global classification scheme. The map was designed by MACBIO as resource for the workshop on bioregions in Feb 2018. Data is based on Yesson et al. (2011) "The global distribution of seamounts based on 30-second bathymetry data and Harris et al. (2014) "Geomorphology of the oceans".
A map showing simply the location of seamounts in Solomon Islands EEZ. The map was developed by MACBIO as resource for the workshop on bioregions in Fab 2018. Data is based on Yesson et al. (2011) "The global distribution of seamounts based on 30-second bathymetry data and Harris et al. (2014) "Geomorphology of the oceans".
Map developed by MACBIO as resource for the bioregions workshop in Feb 2018. Nitrate is an essential resource, which, together with available light, determines the amount of organic matter that can be synthesized by phytoplankton through photosynthesis. Nitrate concentration is also a key variable of biogeochemical and ecosystem models. Data is based on CSIRO Atlas of Regional Seas (CARS).
Dissolved oxygen is a key parameter to trace physical dynamics and to better understand biogeochemical processes in the World Oceans. O2 concentration is always the balance between biological terms (production by phytoplankton, consumption through respiration by all organisms) and ocean atmosphere o2 exchanges (so-called ventilation processes).
The map was developed by MACBIO as resource for the bioregions workshop in Feb 2018. Data is based on Tyberghein L., et al (2011) Bio-ORACLE: a global environmental dataset for marine species distribution modelling.
Map developed by MACBIO as resource for the bioregions workshop in Feb 2018. Data is based on CSIRO Atlas of Regional Seas (CARS).
All living organisms require the nutrients nitrogen and phosphorus for their growth, metabolism and reproduction. Research has demonstrated that phytoplankton productivity in the surface ocean is often limited by the amount of available fixed inorganic nitrogen and available phosphorus.
The map was developed by MACBIO as resource for the bioregions workshop in Feb 2018. Data is pased on CSIRO Atlas of Regional Seas (CARS).
Map of particulate Inorganic carbon in Solomon Islands Oceans. The map was developed by MACBIO as resource for the bioregions workshop in Feb 2018. Data on inorganic carbon is based on CSIRO: Lutz et al 2009.
Map of distribution of particulate organic carbon that represents the concentration of carbon in the ocean.
The map was developed by MACBIO as resource for the bioregions workshop in Feb 2018. Carbon data is based on CSIRO: Lutz et al 2009.
Particulate organic carbon flux represents the rate at which carbon is cycled through the ocean and the factors that may alter the rates of transfer.
The map was developed by MACBIO as resource for the bioregions workshop in Feb 2018. Data is based on CSIOR: Lutz et al. 2009.

There are not perfect data which describe the distribution and abundance of every marine habitat and species in the Pacific. And certainly not at a scale that is useful for national planning in the ocean. Bioregionalisation, or the classification of the marine environment into spatial units that host similar biota, can serve to provide spatially explicit surrogates of biodiversity for marine conservation and management. Existing marine bioregionalisations however, are at a scale that is too broad for national governments in the Pacific to use.
The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.
