1. Exercising Sovereignty Over Canada's North: Arctic Shipping Routes Open

As sea ice melts during the summer months, two major shipping routes have opened in the Arctic Ocean. Every year, the Arctic Ocean experiences the formation and then melting of vast amounts of floating ice, but the rate of overall loss has accelerated. This animation shows the melting of Arctic sea ice from 1 June to 24 August 2011: www.esa.int/images/JunAug_ArcticIceCoverAnim_H.gif. This animation consists of Envisat ASAR mosaics of the Arctic Ocean acquired in mid-August 2011: www.esa.int/images/ASAR_2010-11_Arctic_H.gif. Located in the Canadian Arctic Archipelago, the Northwest Passage can be a shipping short cut between Europe and Asia: www.esa.int/images/2011-08-24_NorthwestPassageCanada_H.jpg. The Canadian Space Agency (CSA) contributed to the development of Envisat.

2. RADARSAT-2 Data Contributes to a New Understanding of Antarctic Terrain

Imagery acquired from the Canadian satellite RADARSAT-2 has enabled the landmark discoveries announced on August 18th by University of California (UCI) researchers. Previously unmapped glaciers of Antarctica have been charted by accessing imagery collected from Canadian, European and Japanese Earth Observation (EO) satellites. Using NASA technology, the researchers have discovered unique terrain features that indicate the direction and velocity of ice in Antarctica. This will provide invaluable insight into ice melt and future sea rise due to climate change. The full continental coverage of Antarctica was made possible due to the unique capabilities of RADARSAT-2 to image left and capture data and information over the central part of the continent. This endeavor was coordinated by the International Polar Year (IPY) Space Task Group and was only possible through the collective effort of the Synthetic Aperture Radar (SAR) mission Coordination Group. International contributors include the CSA, NASA, the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency.

4. Disaster Management Earth Observation Applications: Request For Standing Offer (RFSO) for Rapid Information Products and Services (RIPS) Now Closed

Canada has identified disaster management as one of three key applications domain for the upcoming RADARSAT Constellation Mission (RCM). The CSA RFSO for the Provision of EO based RIPS regarding disaster response and environmental emergency management has closed on August 26th 2011. The purpose of this RFSO is to make available to the CSA and its partners fours standing offers of qualified list of Canadian suppliers that can provide EO-based RIPS to meet the needs of disaster management authorities, when required. These products and services will be used to demonstrate EO capability to support disaster management initiatives. The information will be made available to potential end-users within federal government departments and agencies and those organizations requesting support, for example the Committee on Earth Observation Satellites (CEOS), the Group of Earth Observation (GEO). For more information about the RIPS initiative, please contact guy.aube@asc-csa.gc.ca.

5. Caribbean Satellite Disaster Pilot: Hurricane Season 2011

As the 2011 Atlantic hurricane season reaches its peak, the CSA Earth Observation Applications and Utilization (EOAU) Division continues to support disaster management for affected populations across the Caribbean, including local damage assessment and coastal change detection. CSA is a critical part of the NASA-led Caribbean Satellite Disaster Pilot (CSDP), contributing more than 40 high-resolution RADARSAT-2 scenes have been collected by CSA in preparation for rapid change detection and flood mapping activities. In addition, CSA is leading the CSDP's efforts for longer-term risk mitigation and preparedness, working directly with local authorities in five Caribbean island states. In the coming months, radar imagery will be planned and acquired over affected areas to assist disaster management efforts. The data sets are accessible to accredited CSDP end-users within a very short time. In cooperation with Canadian industry and Caribbean authorities, CSA will also contribute EO expertise and RADARSAT-2 image change detection maps for local damage assessment teams. Canada's contributions are part of the overall GEO Task 'Demonstrating regional end-to-end applications for disaster management which is led by CSA on behalf of the CEOS.

6. Ocean Ecosystem Productivity: Arctic Phytoplankton Summer Bloom Monitored With Canadian Earth Observation Technology

Monitoring the interactions between the oceans and climate with EO satellites provide information on basic productivity of the oceans and how this productivity provides food for fish. It also helps to report on indicators of the health of the ocean ecosystem, its stability and fragility in the face of anthropogenic and natural changes. Cape Nordkinn is the northern point on Nordkinn Peninsula (Barrents Sea) in Norway. The southern area of this deep shelf sea remains mostly ice-free due to the warm North Atlantic Drift. This contributes to its high biological production compared to other oceans of similar latitude. Phytoplanktons are able to convert inorganic compounds such as water, nitrogen and carbon into complex organic materials. With their ability to 'digest' these compounds, they are credited with removing as much carbon dioxide from the atmosphere as their 'cousins' on land – therefore having a profound influence on climate. They are also sensitive to environmental changes, so it is important to monitor and model phytoplankton into calculations of future climate change. To view a phytoplankton bloom captured recently by MODIS (Aqua) on August 14th and by Envisat MERIS on August 17th near Cape Nordkinn, please visit: eoimages.gsfc.nasa.gov/images/imagerecords/51000/51765/BarentsSea_amo_2011226_lrg.jpg, esamultimedia.esa.int/images/imageoftheweek/2011-08-24_AlgaeBloomBarentsSea_H1.jpg. The CSA contributed to the development of Envisat.

7. Precision Farming: Nitrogen Requirement Assessment Through Crop Earth Observation

Through the CSA Government Related Initiatives Program (GRIP), Agriculture and Agri-Food Canada (AAFC) is developing a precision farming project titled "N Watch: Nitrogen Requirement Assessment Through Crop Observation". The ultimate objectives are to make fertilizer management decisions on a regional as well as subfield bases and to improve Canadian farmers' profit and harvest yields while reducing the negative impacts of farming on the environment (water pollution, soil degradation and greenhouse gases emissions). More specifically, this AAFC/GRIP project is to establish the EO data sources and processing steps to include in the information product, to quantify and to qualify the degree of accuracy achieved by the information products in a context of relative, instead of absolute, crop growth assessment. It will also examine the possible integration of the information products into Agri-Environment Services Branch (AESB) operations. The project team will use multiple sets of EO data, including RADARSAT-2, WorldView-2, Rapid-Eye, SPOT-5, GeoEye-1, QuickBird and Ikonos. The future RADARSAT and Sentinels constellations are envisioned for N Watch operations. This GRIP project fits in the Government of Canada national priority areas of the AAFC Science and Innovation Strategy (i.e. Enhancing environmental performance of the Canadian agricultural system). It has the potential to affect how N fertilizer inputs are managed by farmers and regulated by federal and provincial governments.

8. Precision Agriculture: Mapping Soil Drainage Indicators Using RADARSAT-2

Agricultural parcels are made up of soils with different properties and behaviours in terms of productivity potential, development needs and risks for degradation or losses to the environment. Precision agriculture uses a number of technologies, including EO, to manage soil variability within parcels by adjusting the application rates of inputs (fertilizer, lime, pesticides, etc.) or development work (irrigation, drainage, sowing, etc.) to the specific soil conditions. In partnership with the CSA GRIP, AAFC uses RADARSAT-1 and RADARSAT-2 images, as well as optical images, to generate maps of drainage and soil surface texture in the Montérégie region on both the local (farm) and regional (watershed) levels. These raster maps (30 m x 30 m) provide more precise information on the spatial variability of the surface texture class and the soil drainage than vector maps from conventional soil mapping. The project under way, entitled "Soil Property Retrieval Using Multi-Temporal SAR and Expert Knowledge," is directly linked to the Government of Canada's Growing Forward strategic framework and to the GlobalSoilMap.net and GEOSS initiatives. For more information, please contact michel.nolin@agr.gc.ca and guy.aube@asc-csa.gc.ca.

9. Precision Farming: Giving Eyes to Crop Models

Through the CSA GRIP, AAFC is developing a project titled "Adapting cropping systems to climate variations: deriving crop biomass and yield from remote sensing over a region: demonstration and planning phase in eastern Ontario". When it comes to predicting yield and estimating the ecological footprint of crops over a region, crop growth models can be used in conjunction with soil and climate databases. These databases are not capturing all the spatial variations of importance for crop growth. For example, within-field heterogeneous soil properties, rainfall distribution in tens-km radius of a weather station are not fully captured while they influence crop growth. Moreover, detailed management practices (e.g. crop type, seedbed preparation, seeding date, fertilization, weed management, harvest) are unknown, unless individual farmers are interviewed. By using biophysical descriptors derived from multi-temporal EO, such as leaf area index (LAI)over the growing season (2-6 images), key input parameters of crop models can be optimized. The re-initialization of these input model parameters compensates to some extent for the lack of spatial information. Using field subunits defined by field boundaries and soil texture maps for running the crop model, they showed that yield and biomass could be predicted with great accuracy as well as water consumption. The study showed the importance of having access to basic daily climatic data spatially representative of the region of interest to run the crop growth model. Getting better meteorological information from satellite will greatly enhance crop model predictions. For more information, please contact elizabeth.pattey@AGR.GC.CA and guy.aube@asc-csa.gc.ca.

10. Horn of Africa Drought Monitoring: Earth Observation Applications with Soil Moisture and Ocean Salinity (SMOS)

Drought in Somalia, Kenya, Ethiopia and Djibouti is pushing tens of thousands of people from their homes as millions face food insecurity in a crisis visible from space. The SMOS EO satellite shows that the region's soil is too dry to grow crops. The SMOS data shows that Somalia's soil appears dry during the 2011 main rainy season, particularly in the southern agricultural region. The animation, derived from SMOS satellite data, shows soil moisture in the Horn of Africa from April to mid-July 2011. The orange and yellow colouring depicts little to no moisture, while green and blue depict higher levels of soil moisture: download.esa.int/multimedia/earthobservation/smos_somalia_anv2.gif. Canada contributed to the development of SMOS. Array Systems Computing Inc. (Toronto, Canada) in collaboration with the Expert Support Labs (ESL), ESA and the Canadian Space Agency, has successfully developed the SMOS Level 2 Soil Moisture processor.
