Upwelling at the Northern Malacca Straits Intruded into Eastern Indian Ocean 2016


Upwelling event at the Northern Malacca Straits has been identified as one the important ocean phenomena at Southern Andaman Sea and Northern Sumatra. Every year during the winter monsoon, the monsoon driven Ekman Pumping mechanism will bring a large phytoplankton bloom to this particular region. There are two locations where the Ekman Pumping will occur, of the western area of Langkawi and Penang Island, and Northeastern of Sumatra Northern Tip. The west of Langkawi and Penang upwelling event will create greater phytoplanton bloom compare to the Northeastern of Sumatra.

Below are the MODIS Aqua images taken on 26 February 2016.

MODIS Aqua Chlorophyll-a image on 26 Feb 2016

High chlorophyll a water (more than 1 mg/m^3) extended from western Penang and Langkawi Island towards Andaman Sea. Another phytoplankton bloom can be observed off the Northwestern of Sumatra Tip, where it appears like cyclonic eddy. Larger phytoplankton bloom off Penang and Langkawi Island is due to the double enrichment action from both upwelling and nutrient loaded coastal water.

MODIS Aqua Sea Surface Temperature image on 26 Feb 2016

MODIS Aqua Sea Surface Temperature image on 26 Feb 2016

Very distinct sea surface temperature difference can be compared between the upwelling region at the northern tip of Sumatra Island. The upwelling region shows surface temperature around 27.5C, while the surface temperature at non upwelling region around 30C. There are very clear, cooler water and hot water region off the Sumatra Tip. The cooler water distribution pattern was coincided with the cyclonic eddy like phytoplankton bloom pattern. While cooler SST of the upwelling event at western Penang and Langkawi Island is not clear as compared to the Northen Sumatra. The main reason could be the shallow depth, as well as the influence from the warm coastal water.

MODIS Aqua True Color RGB image on 26 Feb 2016

The winter monsoon upwelling is so strong until the phytoplankton bloom can be clearly observed with the MODIS Aqua RGB true color image. The dark green color phytoplankton bloom off Penang and Langkawi Island can be distinguished a part from the milky turbid coastal water. This dark green color phytoplankton bloom one extended into Andaman Sea, and another towards the Northern Sumatra. Another local upwelling at the Sumatra Tip further enhanced this phytoplankton bloom and it turn into an cyclonic eddy like pattern off the Southern of Great Nicobar Island.

Strong Upwelling at Eastern Indian Ocean – Is the Positive Indian Ocean Dipole started?


There is a strong ocean upwelling event along the coast of Southern Java and Sumatra Island as he Modis Aqua satellite observed on 2 September 2015. According to many weather forecast agencies, high possibility of positive Indian Ocean Dipole will occur in accordance to the El Nino in the Pacific Ocean. BOM highlighted that current IOD index is reaching +4 degree, if the IOD index persist or increase, positive IOD will be confirmed for 2015.

PostDoc Opportunity at US EPA


Satellite Remote Sensing of Inland and Estuarine Water Quality
Research Participation Program
Office of Research and Development
National Exposure Research Laboratory
U.S. Environmental Protection Agency (EPA)
Project Description:

A postdoctoral research project training opportunity is currently available at the U.S. Environmental Protection Agency’s (EPA) Office of Research and Development (ORD), National Exposure Research Laboratory (NERL). This appointment will be served in the Environmental Sciences Division (ESD) in Research Triangle Park, North Carolina.

The Environmental Sciences Division (ESD) develops methods for characterizing chemical and physical stressors with special emphasis on ecological exposure. This program builds landscape and regional assessment capabilities through the use of remote sensing and advanced spatial analysis techniques. Research involves the application of advanced monitoring technology to issues involving surface waters at a variety of scales.

This research project is part of a larger collaborative effort between the U.S. EPA, NASA, NOAA and USGS to provide an approach for mainstreaming satellite ocean color capabilities into U.S. fresh and brackish water quality management decisions. The overarching project goal is to support the environmental management and public use of U.S. lakes, reservoirs and estuaries by providing the capability to detect and quantify cyanobacteria blooms using satellite data records. Satellite remote sensing tools may enable policy makers and environmental managers to assess the sustainability of watershed ecosystems, and the services they provide, under current and future land use practices. Satellite technology allows for the development of cyanobacteria early-warning indicators at the local scale with continuous, synoptic national coverage. The research project is structured within a sustainability framework for a more holistic approach including environmental, human health and economic considerations.

The multi-agency collaborative effort has six main components: (1) develop a uniform and systematic approach for identifying cyanobacteria blooms across the contiguous U.S.; (2) evaluate and refine algorithms across satellite platforms; (3) link impacts of landscape changes and bloom events; (4) demonstrate that satellites can link exposure and human health effects in drinking and recreational waters; (5) evaluate the economic value of the satellite early warning system; and (6) disseminate data and training for stakeholders.

The research participant will have a unique opportunity to work within a large multi-disciplinary team to apply satellite ocean color instruments to address management and other issues related to monitoring harmful and nuisance algal blooms nationally. The project will disseminate information derived from ocean color instruments onboard Aqua, Sentinel-3, Sentinel-2 and Landsat through an Android mobile application and the EnviroAtlas. A strategy for evaluation, validation and refinement of algorithms for use with other satellite instruments, such as PACE, will also be developed. The project is on the cutting edge of water quality monitoring and applied satellite operations.

This research training opportunity will involve the research participant in innovative, relevant and impactful research that will integrate the application of satellite remote sensing of water quality with human health, environmental and economic data, and will allow him/her to advance expertise in the use of satellite remote sensing of water quality to improve novel decision support tools such as mobile applications. The research participant will be involved in the collaboration of a large, multi-federal agency team with local and regional water quality managers and will broaden professional networks through peer-reviewed publications and presentations at meetings and conferences.

Applicants must have received a doctoral degree in aquatic ecology, algal ecology, marine ecology, ocean optics, landscape or spatial ecology, and/or a related field within five years of the desired starting date, or completion of all requirements for the degree should be expected prior to the starting date. Experience in computer coding language, (e.g. MATLAB, Python, R, or IDL) and satellite ocean color remote sensing is desired.

The program is open to all qualified individuals without regard to race, sex, religion, color, age, physical or mental disability, national origin, or status as a Vietnam era or disabled veteran. U.S. citizenship or lawful permanent resident status is preferred (but can also hold an appropriate visa status, however, an H1B visa is not appropriate).

The appointment is full-time for one year and may be renewed upon recommendation of EPA and contingent on the availability of funds. The participant will receive a monthly stipend. Funding may be made available to reimburse a participant’s travel expenses to present the results of his/her research at scientific conferences. No funding will be made available to cover travel costs for pre-appointment visits, relocation costs, tuition and fees, or a participant’s health insurance. The participant must show proof of health and medical insurance. The participant does not become an EPA employee.
