Ocean Optics Summer Class - July 7 – August 2, 2013 at the University of Maine, Darling Marine Center

Ocean Optics Summer Class: 

Calibration and validation of ocean color remote sensing. 

July 7 – August 2, 2013 at the Darling Marine Center

 An intensive four-week, cross-disciplinary, graduate-level course in Optical Oceanography will be offered at the University of Maine, Darling Marine Center in summer 2013.  This class is a continuation of the Optical Oceanography course first offered at the Friday Harbor Laboratories in 1985 and more recently at the Darling Marine Center.  Past graduates are many of today's leaders in oceanography.

 The major theme of the course is calibration and validation of ocean color remote sensing. The course will provide students with a fundamental knowledge of ocean optics and optical sensor technology that will enable them to make quality measurements, be able to assess the uncertainties associated with the measurements and compare these data with remotely sensed ocean color measurements and products derived from them. The course is sponsored by NASA and the University of Maine, with the goal of preparing a new generation of oceanographers trained in the use of optics to study the oceans.

Course elements include:

• lectures on the basic theory of the light interaction with matter in aquatic environments, ocean color remote sensing and its inversion, sensor design and function, and ocean biogeochemistry; computation and propagation of measurement uncertainties;

• laboratory sessions using optical instrumentation and radiative transfer software;

• field sampling of optical and biogeochemical variables in the environmentally diverse waters of coastal Maine;

• analysis of optical and biogeochemical data sets; and

• collaborative student projects.

See: http://misclab.umeoce.maine.edu/~optics/ for previous class content and activities.

 Instructors (alphabetical):  Emmanuel Boss (coordinator), Curt Mobley, Mary Jane Perry, Collin Roesler, Ken Voss, Jeremy Werdell and Ron Zaneveld.

 Dates:  July 7– August 2nd, 2013

Costs: Scholarships for Tuition, room and board and academic credits are available. Please indicate if you require one.

 Registration: Registration deadline is March 1st, 2013, notification by April 1st, 2013. Registration at http://server.dmc.maine.edu/courses.html

 Acceptance criteria:  likely impact of the class on the individual's career, transcripts, letter from the academic advisor/supervisor, and diversity.  While the majority of the class will likely be composed of early career graduate students, advanced students and post-doctoral fellows will be considered for admission.

Summer Satellite Remote Sensing Training Course - Cornell University, Ithaca New York

Summer Satellite Remote Sensing Training Course
May 31 - June 14, 2013, Cornell University, Ithaca New York
A two-week summer satellite training course is being offered once again to marine scientists who have modest or no prior experience with satellite remote sensing techniques. The course is highly methods-oriented and intended to give participants the practical skills needed to work independently to acquire, analyze and visualize large data sets derived from a wide variety of ocean satellite sensors. Strong emphasis is given to ocean color remote sensing and the use of NASA's SeaDAS software (both version 6 and 7-beta) to derive mapped imagery of geophysical parameters (e.g., chlorophyll or CDOM) from raw SeaWiFS, MODIS, MERIS and VIIRS data.  The course also covers image analysis methods to work with satellite imagery of sea surface temperature, ocean wind speed and sea surface height.  Developing good IDL programming skills for data analysis and visualization is a central component of the course. A new topic being added this year is a basic introduction to Python programming and running SeaDAS with relatively simple Python scripts to batch process ocean color data from Level-1 to Level-3.

MODIS-Aqua ocean color climatologies available on Giovanni

MODIS-Aqua ocean color climatologies allow 10 years of anomaly analysis

New insights possible from higher spatial resolution and new data products

 

The incorporation of the recently released 10-year climatology of ocean color data from NASA's Moderate Resolution Imaging Spectroradiometer on the Aqua satellite (MODIS-Aqua) allowed the Giovanni data system to provide anomaly analysis for this important ocean data set.

The Earth Observing System Aqua satellite was launched in early 2002, and the onboard MODIS instrument began collecting data on July 4, 2002. Thus, at the end of June 2012, there were 10 years of monthly averaged MODIS data for each month of the year. The Ocean Biology Processing Group (OBPG) at Goddard Space Flight Center updates their monthly climatology files as each new month is completed. In July 2012, the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) acquired these monthly climatology files to create a 10-year climatology base period for the Giovanni data system.

With the climatology files in Giovanni, researchers could then examine these climatological averages, or use the new data for anomaly analysis. The latter enhances the detection of unusual events in any long-term data set, by comparing data from a selected period to the average of the data for a much longer period (i.e., "base period"). For ocean color data in Giovanni, anomaly analysis has been available for the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) for several years, but the SeaWiFS mission ended in December 2010. For MODIS-Aqua ocean color climatology data, the mission is still continuing. Furthermore, MODIS-Aqua data are available at 4 km spatial resolution, rather than the 9 km spatial resolution of SeaWiFS data.

Several new data products are available from MODIS-Aqua, including normalized fluorescence line height (nFLH), colored dissolved organic matter (CDOM) Index, absorption coefficients for dissolved and detrital matter (acdm) and phytoplankton (aph), backscattering coefficient for particulate matter (bbp), and euphotic depth (Zeu). The MODIS-Aqua climatology data also provide remote-sensing reflectance data at several more wavelengths than were available from SeaWiFS.

Giovanni's anomaly analysis capability allows users to examine monthly anomalies, and any other time period up to a year in duration. So, for example, it is possible to average data for a season (such as the spring months of March, April, and May of a particular year) and compare this three-month average to the climatological average for March through May.

2至3月進入高峰期•沙巴紅潮區貝類海產或有毒

星洲日报, 7 Jan 2013

(沙巴‧亞庇6日訊)沙巴漁業局總監雷納卡力今日勸告西海岸魚販勿售賣源自吧巴、斗亞蘭、布打丹和亞庇一帶海域,以及瓜拉班尤的西多博湖的貝殼類海產或小魚,否則可被衛生部執法當局援引食品法令檢舉和提控。

他說,由於上述海域出現紅潮現象,有關海產和小魚或已受到毒素污染,食用後可對人体造成生命威脅,尤其在來臨的2至3月份的高峰期。

他今日受詢2名公眾疑食用了遭紅潮毒素污染的貝殼海產喪命時,再次提醒公眾在紅潮象期間,勿進食可能受污染的貝殼類海產或小魚。

他說,若公眾誤食有關的貝殼類海產或小魚,或出現紅潮毒素的病徵,應儘速到最靠近的醫院求診,以免發生不幸事件。

他表示,該局在去年11月時就發現了紅潮現象,依據過往的歷史記錄,此現象將會持續,並在來臨的2至3月時進入高峰期,最後在6月份左右才完全消失。

沙巴衛生總監克麗絲狄娜昨日證實,州內有6人因感染紅潮毒素而送院就醫,有2人不幸喪命。

她說,經調查後,上述就醫的人士是進食了源自實邦加海域的蛤蜊,而出現食物中毒、頸部刺痛、嘔吐、暈眩和呼吸急速的徵狀。喪命的2人則出現嚴重的過敏休克和昏迷症狀,最後不幸喪命。

她勸告公眾在紅潮期間,暫時不要食用源自出現紅潮現象的貝殼類海產,至於魚、蝦、螃蟹和烏賊,則安全食用。

Sabah issues red tide alert

The Star, 7 Jan 2013

KOTA KINABALU: The deadly algae bloom, commonly known as the red tide phenomenon, will peak in the next two months statewide.

Sabah Fisheries Department director Rayner Stuel Galid said that red tide was recorded in November last year and will begin peaking between this month and February before tailing off by June.

"We are conducting daily tests and have found high toxicity in the west coast," he said, adding that anything above 400 mouse units (MU) was considered dangerous.

Galid advised people to avoid eating oysters, mussels, cockles and any type of clam though other marine products like fish, prawns and crabs were safe for consumption.

He said the red tide has been seen in waters off Papar, Kota Kinabalu and Tuaran in the west coast while they have not received any reports in the east coast.

Two boys, aged 14 and nine, died from paralytic shellfish poisoning after consuming cockles on Jan 1.

The older boy died a day after eating the shellfish while the second boy died on Friday, according to Sabah Health Department director Dr Christina Rundi in a statement.

The boys had collected the cockles from the seafront at Sepanggar about 30km from here and were said to have eaten them raw.

Galid said clams, even when cooked, are still poisonous and should be avoided during the red tide season.

Red tide is a natural phenomenon whereby algae form large colonies which produce harmful effects to marine life. The density of the algae colours the surface of the sea red.
