The Great New England Hurricane of 1938
CAT 3 - September 21, 1938
The Great New England Hurricane of 1938 was one of the most destructive and powerful storms ever to strike Southern New England. This system developed in the far eastern Atlantic, near the Cape Verde Islands on September 4. It made a twelve day journey across the Atlantic and up the Eastern Seaboard before crashing ashore on September 21 at Suffolk County, Long Island, then into Milford, Connecticut. The eye of the hurricane was observed in New Haven, Connecticut, 10 miles east of Milford. The center made landfall at the time of astronomical high tide, moving north at 50 mph. Unlike most storms, this hurricane did not weaken on its way toward Southern New England, due to its rapid forward speed and its track. This kept the center of the storm over the warm waters of the Gulf Stream.
Sustained hurricane force winds occurred throughout most of Southern New England. The strongest winds ever recorded in the region occurred at the Blue Hill Observatory with sustained winds of 121 mph and a peak gust of 186 mph. Sustained winds of 91 mph with a gust to 121 mph was reported on Block Island. Providence, Rhode Island recorded sustained winds of 100 mph with a gust to 125 mph. Extensive damage occurred to roofs, trees and crops. Widespread power outages occurred, which in some areas lasted several weeks. In Connecticut, downed power lines resulted in catastrophic fires to sections of New London and Mystic. The lowest pressure at the time of landfall occurred on the south side of Long Island, at Bellport, where a reading of 27.94 inches was recorded. Other low pressures included 28.00 inches in Middletown, Connecticut and 28.04 inches in Hartford, Connecticut.
The hurricane produced storm tides of 14 to 18 feet across most of the Connecticut coast, with 18 to 25 foot tides from New London east to Cape Cod. The destructive power of the storm surge was felt throughout the coastal community. Narragansett Bay took the worst hit, where a storm surge of 12 to 15 feet destroyed most coastal homes, marinas and yacht clubs. Downtown Providence, Rhode Island was submerged under a storm tide of nearly 20 feet. Sections of Falmouth and New Bedford, Massachusetts were submerged under as much as 8 feet of water. All three locations had very rapid tides increased within 1.5 hours of the highest water mark.
Rainfall from this hurricane resulted in severe river flooding across sections of Massachusetts and Connecticut. Three to six inches fell across much of western Massachusetts and all but extreme eastern Connecticut. Considerably less rain occurred to the east across Rhode Island and the remainder of Massachusetts. The rainfall from the hurricane added to the amounts that had occurred with a frontal system several days before the hurricane struck. The combined effects from the frontal system and the hurricane produced rainfall of 10 to 17 inches across most of the Connecticut River Valley. This resulted in some of the worst flooding ever recorded in this area. Roadways were washed away along with sections of the New York, New Haven, and Hartford Railroad lines. The Connecticut River, in Hartford reached a level of 35.4 feet, which was 19.4 feet above flood stage. Further upstream, in the vicinity of Springfield, Massachusetts, the river rose to 6 to 10 feet above flood stage, causing significant damage. A total of 8,900 homes, cottages and buildings were destroyed, and over 15,000 were damaged by the hurricane. The marine community was devastated. Over 2,600 boats were destroyed, and over 3,300 damaged. Entire fleets were lost in marines and yacht clubs along Narragansett Bay. The hurricane was responsible for 564 deaths and at least 1,700 injuries in Southern New England. Damage to the fishing fleets in Southern New England was catastrophic. A total of 2,605 vessels were destroyed, with 3,369 damaged.

Massachusetts | Wikipedia audio article
Massachusetts ( (listen), ), officially the Commonwealth of Massachusetts, is the most populous state in the New England region of the northeastern United States. It is bordered by the Atlantic Ocean to the east, the states of Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state is named after the Massachusett tribe, which once inhabited the east side of the area, and is one of the original thirteen states. The capital of Massachusetts is Boston, which is also the most populous city in New England. Over 80% of Massachusetts's population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry. Originally dependent on agriculture, fishing and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the 20th century, Massachusetts's economy shifted from manufacturing to services. Modern Massachusetts is a global leader in biotechnology, engineering, higher education, finance, and maritime trade.Plymouth was the site of the first colony in New England, founded in 1620 by the Pilgrims, passengers of the Mayflower. In 1692, the town of Salem and surrounding areas experienced one of America's most infamous cases of mass hysteria, the Salem witch trials. In 1777, General Henry Knox founded the Springfield Armory, which during the Industrial Revolution catalyzed numerous important technological advances, including interchangeable parts. In 1786, Shays' Rebellion, a populist revolt led by disaffected American Revolutionary War veterans, influenced the United States Constitutional Convention. In the 18th century, the Protestant First Great Awakening, which swept the Atlantic World, originated from the pulpit of Northampton preacher Jonathan Edwards. In the late 18th century, Boston became known as the Cradle of Liberty for the agitation there that led to the American Revolution.
The entire Commonwealth of Massachusetts has played a powerful commercial and cultural role in the history of the United States. Before the American Civil War, Massachusetts was a center for the abolitionist, temperance, and transcendentalist movements. In the late 19th century, the sports of basketball and volleyball were invented in the western Massachusetts cities of Springfield and Holyoke, respectively. In 2004, Massachusetts became the first U.S. state to legally recognize same-sex marriage as a result of the decision in Goodridge v. Department of Public Health by the Massachusetts Supreme Judicial Court. Many prominent American political dynasties have hailed from the state, including the Adams and Kennedy families. Harvard University in Cambridge is the oldest institution of higher learning in the United States, with the largest financial endowment of any university, and Harvard Law School has educated a contemporaneous majority of Justices of the Supreme Court of the United States. Kendall Square in Cambridge has been called the most innovative square mile on the planet, in reference to the high concentration of entrepreneurial start-ups and quality of innovation which have emerged in the vicinity of the square since 2010. Both Harvard University and the Massachusetts Institute of Technology, also in Cambridge, have been ranked among the most highly regarded academic institutions in the world. Massachusetts' public school students place among the top nations in the world in academic performance, and the state has been ranked as one of the top states in the nation for citizens to live, as well as one of the most expensive.

JBS Haldane Lecture 2018 : Prof. John Tresch - Barnum, Bache and Poe.
JBS Haldane Lecture 2018 : Prof. John Tresch - Barnum, Bache and Poe: Forging Science in a Media Revolution.
The Department of Science and Technology Studies holds its second JBS Haldane Lecture of 2018 with Professor John Tresch of The Warburg Institute, discussing the history of PT Barnum, Alexander Dallas Bache, and Edgar Allen Poe - their relation to developments in science during that era, and the similarities with present-day America.
The JBS Haldane Lecture Series is the flagship public lecture series from the Department of Science and Technology Studies at UCL. Named in honour of UCL Professor JBS Haldane, a polymath not only in the life sciences but also in science communication and science policy, the department aims to hold these biannually. More details can be found on the STS Website at
Abstract:
Today’s scientific and political institutions face severe challenges, nowhere more visibly than in the USA— where scientific evidence of climate change is scorned by a media-obsessed president whose heroes include the nativist demagogue Andrew Jackson and the con-artist P.T. Barnum. This lecture returns to the 1830s and 1840s, the era of Barnum, Jackson, and a communications revolution, to explore competing visions of the cosmos and of the relation between science and the demos in a moment of turmoil. Two opposed tendencies characterised antebellum public culture: first, a sharp increase in printed communication, with periodicals, audiences, styles, and authors exploding in number and diversity; second, a coordinated movement by educated elites to control knowledge through centralised and hierarchical institutions. In the sciences, the Lyceum movement and Barnum’s “American Museum” typified the first, while the U.S. Coast Survey, directed by Benjamin Franklin’s great grandson, the West Point-educated polymath, Alexander Dallas Bache, exemplified the second.
The work of Edgar Allan Poe (1809-1849) was shaped by both tendencies. Trained at West Point, Poe wrote frequently about the sciences, even as he invented new forms of literary sensationalism. He “forged” American science and letters in two senses: by supporting projects to establish a unified and regulated intellectual infrastructure, and by crafting believable fakes which fed popular uncertainty about authority over knowledge. Poe thus offers astute, prophetic, and dramatically conflicted commentary on science, its publics, and the stories it tells.

SUMMARY
=======
The Kerguelen Islands ( or ; in French commonly Îles Kerguelen but officially Archipel des Kerguelen, pronounced [kɛʁɡelɛn]), also known as the Desolation Islands (Îles de la Désolation in French), are a group of islands in the Antarctic constituting one of the two exposed parts of the Kerguelen Plateau, a large igneous province mostly submerged by the southern Indian Ocean. They are among the most isolated places on Earth, located 450 km (280 mi) northwest of the uninhabited Heard Island and McDonald Islands and more than 3,300 km (2,100 mi) from Madagascar, the nearest populated location (excluding the Alfred Faure scientific station in Île de la Possession, about 1,340 km (830 mi) from there, and the non-permanent station located in Île Amsterdam, 1,440 km (890 mi) away). The islands, along with Adélie Land, the Crozet Islands, Amsterdam, and Saint Paul Islands, and France's Scattered Islands in the Indian Ocean are part of the French Southern and Antarctic Lands and are administered as a separate district.
The main island, Grande Terre, is 6,675 km2 (2,577 sq mi) in area and is surrounded by a further 300 smaller islands and islets, forming an archipelago of 7,215 km2 (2,786 sq mi). The climate is raw and chilly with frequent high winds throughout the year. The surrounding seas are generally rough and they remain ice-free year-round. There are no indigenous inhabitants, but France maintains a permanent presence of 45 to 100 scientists, engineers and researchers. There are no airports on the islands, so all travel and transport from the outside world is conducted by ship.

SUMMARY
=======
Timeline of United States discoveries encompasses the breakthroughs of human thought and knowledge of new scientific findings, phenomena, places, things, and what was previously unknown to exist. From a historical stand point, the timeline below of United States discoveries dates from the 18th century to the 21st century, which have been achieved by discoverers who are either native-born or naturalized citizens of the United States.
With an emphasis of discoveries in the fields of astronomy, physics, chemistry, medicine, biology, geology, paleontology, and archaeology, United States citizens acclaimed in their professions have contributed much. For example, the Bone Wars, beginning in 1877 and ending in 1892, was an intense period of rivalry between two American paleontologists, Edward Drinker Cope and Othniel Charles Marsh, who initiated several expeditions throughout North America in the pursuit of discovering, identifying, and finding new species of dinosaur fossils. In total, their large efforts resulted in when 142 species of dinosaurs being discovered. With the founding of the National Aeronautics and Space Administration (NASA) in 1958, a vision and continued commitment by the United States of finding extraterrestrial and astronomical discoveries has helped the world to better understand our solar system and universe. As one example, in 2008, the Phoenix lander discovered the presence of frozen water on the planet Mars of which scientists such as Peter H. Smith of the University of Arizona Lunar and Planetary Laboratory (LPL) had suspected before the mission confirmed its existence.

Syrian Kurds Cut IS Supply Line Near Iraq; Fears for Christians Mount
Kurdish militia pressed an offensive against Islamic State in northeast Syria on Wednesday, cutting one of its supply lines from Iraq, as fears mounted for dozens of Christians abducted by the hardline group. According to the Syrian Observatory for Human Rights, which tracks the conflict, at least 90 Assyrian Christians were seized from villages in Hasaka province in a mass abduction coinciding with the offensive in the same region by Kurdish forces backed by U.S.-led air strikes. The Syriac National Council of Syria put the figure as high as 150.
Don ANDERSON 3/28/18 New Applications of Autonomous Biosensors
Full title: New Applications of Autonomous Biosensors in Harmful Algal Bloom (Red Tide) Research and Monitoring
About the Speaker
Don Anderson is a Senior Scientist in the Biology Department of the Woods Hole Oceanographic Institution. He earned three degrees from MIT – a BS in Mechanical Engineering in 1970, and a MS (1975) and PhD in Civil and Environmental Engineering in 1977. He joined the scientific staff at WHOI in 1978. Anderson is the former director of WHOI’s Coastal Ocean Institute (COI), and presently serves as Director of the Cooperative Institute for North Atlantic Research (CINAR). Anderson also serves as Director of the U.S. National Office for Harmful Algal Blooms.
Anderson’s research focus is on toxic or harmful algal blooms (HABs), commonly called “red tides”. His research ranges from molecular and physiological studies of growth, sexuality, and toxin production to the large-scale oceanography and ecology of the “blooms” of these microorganisms, including numerical modeling, forecasting, and a range of monitoring and management strategies, many reliant on novel instrumentation and biosensors. Along with an active field and laboratory research program, Anderson is heavily involved in national and international program development for research, monitoring, and management of red tides, marine biotoxins, and HABs. He has testified multiple times before Congressional committees, and has been actively involved in legislation and appropriations related to HABs and hypoxia. He is also an advisor to multiple foreign countries and international aid organizations in the evaluation or creation of management programs for HABs.
About the Lecture
Blooms of the toxic dinoflagellate Alexandrium fundyense cause recurrent outbreaks of paralytic shellfish poisoning (PSP) in the Gulf of Maine region of the U.S. The outbreaks can be widespread, covering hundreds of km of coastline, or localized in small embayments and estuaries. In recent years, our studies of Alexandrium dynamics in both of these systems have incorporated two novel biosensors – the Environmental Sample Processor (ESP) and the Imaging FlowCytobot (IFCB). The ESP uses molecular assays to detect and analyze cells and toxins whereas the IFCB is an automated underwater microscope. This talk will summarize the results and lessons from multiple years of ESP and IFCB deployments in both systems. For the Gulf of Maine work, a new application is highlighted – the estimation of shellfish flesh toxicity at nearby shore stations using ESP-derived cell counts in coastal waters. Most recently we have co-deployed the ESP and the IFCB from a specially built observatory raft. These instruments have typically been deployed separately, but in 2016, were used concurrently during a major A. fundyense bloom for the first time. Data collected from each of these instruments are transmitted to our lab in near real-time and we have begun leveraging this data stream for targeted, adaptive sampling of different A. fundyense life cycle stages. One example is our use of a newly developed High-Speed Microscale Imaging System (HSMIS) that is able to record A. fundyense swimming without interference from wall effects and sample heating, both factors that are inherent to traditional microscopy. Together, these new technologies are providing extraordinary new insights into the rate processes underlying A. fundyense blooms. Specifically, field populations of Alexandrium cells swim and migrate faster (1.3 - 2X), divide faster (up to 2X), produce more gametes (up to 4X) and are more toxic (4X) than indicated from past culture-based experiments using isolates from these same waters. The implications of these findings are profound as it is clear that culture-based assessments have substantially underestimated the true growth and toxigenic potential of natural blooms of Alexandrium. Clearly, sensors like these can play a significant role in HAB research, monitoring, and management.
