The Plymouth Marine Laboratory (UK) will be hosting the Annual Challenger Society and RSPSoc – Marine Optics Special Interest Group meeting on 16-17 December 2013. The meeting will focus on the science and technology behind optical marine measurements collected both in situ and remotely, and their application to marine biogeochemistry.
A training course in Detection of HABs in Southeast Asia by Remote Sensing: Operational Warning and Regional Monitoring Protocols will be offered by the Nippon Foundation/POGO AWI Center of Excellence and will take place at the University of the Philippines from 24 to 15 March 2014. The course is open to 15-20 participants from developing countries within SE Asia area. See https://sites.google.com/site/habseatraining/ for more information.
Humanitarian OpenStreetMap Team coordinates mapping effort after enormous storm devastated country
The Guardian, 15 Nov 2013
More than 700 volunteers have collaborated to provide rescue workers with high quality maps of areas in the Philippines hit by typhoon Haiyan.
Working on OpenStreetMap, a collaboratively created map of the world – like Wikipedia, but for cartographers – the volunteers have made over 1.5m changes, providing information for humanitarian aid workers on the ground and updating maps to reflect damage from the storm.
The work is co-ordinated by the Humanitarian OpenStreetMap Team (HOT), a volunteer group which lets disaster relief workers set tasks for mapmakers at home. Users who want to help out can log-in to the tasking manager, where they are presented with a list of requests from the team.
Most of these are as simple as tracing the road network of an affected area from pre-existing satellite imagery. One asks users to trace the backbone road network for Masbate Island, in the north of the affected area; another asks the state of buildings and roads in Roxas City, in the west.
The biggest tasks call for huge areas to be covered in exacting detail using pictures of what the area looks like after the storm.
“Use new satellite imagery to trace buildings, infrastructure, areas, natural features and other important visible features of the city of Ormoc,” lists one requests, as well as “map the current state of Tacloban City area after Typhoon Haiyan inflicted heavy damage to buildings, infrastructure and areas”.
With post-typhoon satellite imagery, the volunteers have the task of checking their traced maps against the reality of the situation on the ground. Structures can be marked as damaged or destroyed, and so the volunteers can begin the odd work of undoing the mapping they have already done.
Already, the mapping is showing results. A picture shared by the Red Cross’s Robert Banick shows the massive increase in detail on a map of Tacloban City after volunteers started filling in the gaps:
The Red Cross has been using volunteers to improve their maps of under-charted areas since the Haitian earthquake in 2010.
Then, OpenStreetMap users improved maps of Port-au-Prince from the barest outline of the major roads in the area to a fully-detailed map of all the roads in the city and its outlying slums .
Thanks to the efforts of the HOT, responders on the ground have been provided with daily updated downloads for GPS systems, and can use the Field Papers service to print physical atlases of the area, for places where connectivity may be low to non-existent.
Applications are now open for the Second IOCCG Summer Lecture Series, which will take place in Villefranche-sur-Mer, France from 21 July to 2 August 2014. This course is dedicated to high-level training in the fundamentals of ocean optics, bio-optics and ocean colour remote sensing. A number of distinguished scientists have been invited to provide lectures on cutting edge research, focusing on current critical issues in ocean colour science. Students will be given ample opportunity to meet with the lecturers for in-depth discussions on various pre-selected topics, as well as their own scientific research. As was done for the past Summer Lecture Series, all the lectures will be video recorded and made available online. These recorded lectures are a valuable training resource and have been downloaded thousands of times by students from around the world.
Nining Sari Ningsih,Noviani Rakhmaputeri,Agung B. Harto, 2013. Upwelling variability along the southern coast of Bali and in Nusa Tenggara waters. Ocean Science Journal, Volume 48, Issue 1, pp 49-57. DOI 10.1007/s12601-013-0004-3.
Spatial and temporal variation of upwelling along the southern coast of Bali and in the Nusa Tenggara waters — Indonesia was studied by using satellite image data of sea surface temperatures and chlorophyll-a from September 1997 to December 2008. This study clearly reveals annual upwelling in the regions from June to October, associated with the southeast monsoon cycle, with the sea surface temperature (chlorophyll-a concentration) being colder (higher) than that during the northwest monsoon. In addition, this study also shows that the upwelling strength is controlled remotely by ENSO and IOD climate phenomena. During El Niño/positive IOD (La Niña/negative IOD) periods, the Bali — Nusa Tenggara upwelling strength increases (decreases).
