Worldwide GLOBE at Night 2018 Campaign for December commences -- The twelfth in a series of GLOBE at Night citizen-science campaigns for 2018 will commence this Thursday (29 November) and continue through Saturday, 8 December. GLOBE at Night is a worldwide, hands-on science and education program designed to encourage citizen-scientists worldwide to record the brightness of their night sky by matching the appearance of a constellation with the seven magnitude/star charts of progressively fainter stars. These constellations are Perseus in the Northern Hemisphere and Grus for the Southern Hemisphere. Activity guides are also available. The GLOBE at night program is intended to raise public awareness of the impact of light pollution. The first series in the 2019 campaign is scheduled for 29 December-7 January 2019. [GLOBE at Night]

"El Niño ALERT; chance of El Niño in spring increases to 70% Forecasters with the Australian Bureau of Meteorology recently issued an updated ENSO forecast from a Southern Hemisphere perspective. They reported that the tropical Pacific had warmed during the last two weeks, with sea surface temperatures reaching the El Niño levels. However, some of the atmospheric indicators still suggested neutral conditions. However, the most of international forecast models indicated additional warming of the Pacific, which suggests El Niño conditions would be maintained until March 2019. Therefore, they have maintained their Bureau's ENSO Outlook as an El Niño ALERT, which means that an approximately 70% chance exists for the occurrence of an El Niño for the next few months, or roughly triple the normal likelihood.

Role of weather in the Pearl Harbor attack of 1941 -- Although the weather at Pearl Harbor on the leeward side of Hawaii's Island of Oahu on the morning of Sunday, 7 December 1941, was relatively pleasant when the US Navy base was attacked by Japanese aircraft and submarines, the weather did play a role during the days preceding the attack. Six Japanese aircraft carriers left Japan's Kure Naval Base in late November 1941 and travelled essentially undetected across the western North Pacific under the cover of unsettled weather associated with several large storms moving across the Aleutians and the Bering Sea that had cold fronts trailing to the southwest across the North Pacific. One of the storms did scatter the ships over several hundred miles, but did regroup with minimal use of radio communication. The Japanese carrier fleet came to a staging point within 275 miles north of Hawaii, where they launched their attack aircraft early Sunday morning. When the two waves of more than 350 aircraft took off from the carriers in the predawn darkness, strong winds were helping produce rough seas. These aircraft flew through and above a thick deck of low clouds until reaching the leeward side of Oahu, where the skies cleared because of the light northeasterly trade winds descending the slopes of the mountain range. The pilots used the local radio stations
The weather also played a role in the planning, as the Japanese government sent codes to their overseas diplomats using bogus weather reports involving wind directions to announce which countries with which it was cutting diplomatic ties.

Ocean in the News:

FROM LAST WEEK ==>
Eye on the Tropics -- No organized tropical cyclones were detected across any of Earth’s ocean basins during the last week.
Eye on the tropics -- During the last week, tropical cyclone activity was limited to the Indian Ocean basin:

In the northern Indian Ocean basin, near the end of last week Tropical Cyclone Ockhi formed near Sri Lanka. Over this past weekend Ockhi intensified into a category 3 cyclone on the Saffir-Simpson Scale for a short time as it traveled toward the north-northwest across the southeastern Arabian Sea offshore of the southwestern coast of India. Torrential rain associated with Ockhi fell across western India. As of early Monday (local time), Cyclone Ockhi was traveling northward as it was approximately 780 miles to the south of Karachi Pakistan. Current forecasts indicate that Cyclone Ockhi would slowly curve toward the northeast and weaken before reaching the northwest coast of India. Consult the NASA Hurricane Page has satellite images and additional information on Tropical Cyclone Ockhi.
In the southern Indian Ocean Basin, Tropical Storm Dahlia formed late last week approximately 1000 miles to the north-northwest of Learmonth, Australia. Dahlia traveled to the southeast and then to the south toward the northwestern coast of Australia over this past weekend. Tropical Storm Dahlia began weakening as of early Monday (local time) as it was located approximately 460 miles to the north-northwest of Learmonth, Australia. Dissipation was anticipated by late Monday. The NASA Hurricane Page has additional information and satellite images on Tropical Storm Dahlia.

Additional summaries of 2017 hurricane seasons in North Atlantic basins -- At the end of the official 2017 hurricane season in the North Atlantic, eastern North Pacific and central North Pacific basins last Thursday (30 November 2017), NOAA scientists issued their preliminary assessment of this hurricane season in the Atlantic basin. They reported that the Atlantic basin experienced an extremely active season, not only in terms of the number of named tropical cyclones (tropical storms and hurricanes), but also upon the magnitude of a parameter noted as the "Accumulated Cyclone Energy" index, which measures the combined intensity and duration of the storms during the season. The scientists also noted that investments in research and forecasting during recent years have paid dividends in more accurate predictions of tropical cyclone tracks in 2017. A four-and-a-half-minute video was made of the 2017 hurricane season using an animation of satellite images obtained from the NOAA GOES-East satellite. [NOAA News]

Annual national fisheries report for 2016 is released -- NOAA Fisheries recently released their annual Fisheries of the United States 2016 (FUS2016) report indicating commercial and recreational fisheries remain a strong contributor to the entire national economy. US seafood landings at the nation's fishing ports in the calendar year 2016 were slightly lower than in 2015, but the value of these landings were slightly higher. US fishers landed 9.6 billion pounds of fish and shellfish in 2016 that were valued at $5.3 billion. In addition, 9.6 million recreational saltwater anglers took 63 million marine fishing trips during the year. The report reveals that Dutch Harbor, AK and New Bedford, MA remained the top fishing ports for another year, running their dominance to at least 19 years. Americans consumed 4.5 billion pounds of seafood. The report also revealed that the average American consumed 14.9 pounds of fish and shellfish in 2016, which marked a decrease of 0.6 pounds of fish than in 2015. [NOAA News]

Come and explore the deep waters of the Gulf of Mexico on the web -- For the next two and a half weeks, the public is invited to watch dives made by the remotely operated vehicle (ROV) Deep Discoverer from the NOAA Ship Okeanos Explorer as it explores the deep-sea ecosystems of the Gulf of Mexico. The exploration is being undertaken as part of the possible expansion of NOAA's Flower Garden Banks National Marine Sanctuary offshore of Galveston, TX. The Okeanos Explorer has real-time broadband satellite communications that will permit the public to view photographs and videos collected by the ROVs in essentially real-time.

The many uses of ocean surveys are revealed -- NOAA's National Ocean Service posted a feature article entitled "Ping Once, Use Many Times" that describes how hydrographic data collected by modern-day NOAA hydrographic ships can be used for many purposes in addition to updating nautical charts. Some examples of other uses include the mapping of habitats for marine life and the mapping fault lines and mud volcanoes. [NOAA National Ocean Service News]
Multiple models provide new guidance to mitigate "Dead Zone" in Gulf of Mexico -- Several models that included 3-D, time-variable models and an ensemble of regression-based models were the focus of attention at a recent meeting of the Mississippi River/Gulf of Mexico Hypoxia Task Force Coordinating Committee. The results from these models offered the task force new guidance on the levels of watershed nutrient reduction needed to mitigate the northern Gulf hypoxic zone, also known as the "Dead Zone."

Area around Norfolk and Hampton Roads in Virginia is sinking unevenly -- Researchers from NASA's Jet Propulsion Laboratory and Virginia's Old Dominion University who analyzed synthetic aperture radar images acquired between 2007 and 2011 by the Japan Aerospace Exploration Agency's ALOS-1 satellite have found variations in subsidence in the land surface around Virginia's Norfolk and Hampton Roads, with some locations sinking at rates ranging between seven and ten times faster than other area locations. In Hampton Roads, the rate of relative sea level rise due to sinking land and rising sea has been approximately one inch in five years. [NASA Jet Propulsion Laboratory News]
Satellite sees plume of sediment from rivers entering East China Sea -- A natural-color image obtained from data collected by the MODIS sensor onboard NASA's Terra satellite reveals a large plume of suspended sediment that had flowed out of several large rivers in China moving out over the Great Yangtze Bank and then extending into the East China Sea. The plume is most prominent on satellite imagery during the winter months and could be the result of tides lifting sediments from the bottom of the Great Yangtze Bank at a time when the temperature and salinity of the waters off the coast of China create an environment that permits vertical mixing.
