That led to record amounts of water carrying large amounts of fertilizer and other nutrients downriver, it said. The nutrients feed algae, which die and then decompose on the sea floor, using up oxygen from the bottom up in an area along the coasts of Louisiana and Texas. The low-oxygen, or hypoxic, area is likely to cover about 7, square miles 20, square kilometres — roughly the size of Slovenia and all the land in Massachusetts, NOAA said. A Louisiana-based team has estimated the dead zone will be 8, square miles 22, square kilometres. A task force of federal, tribal and state agencies from 12 of the 31 states that make up the Mississippi River watershed set a goal nearly two decades ago of reducing the dead zone from an average of about 5, square miles 15, square kilometres to an average of 1, 4, The record set in is 8, square miles 22, square kilometres. Scientists had said earlier that widespread flooding made a large dead zone likely this year. Related Stories Can plastic made from seaweed solve ocean pollution? Related Links Read the news release.

Using Gammex RMI and CIRS phantoms for twenty four ultrasound systems in the five hospitals the results of penetration depth, distance accuracy, image uniformity, dead zone and axial resolution were reported in this study. On the other hand, a dataset of 35 pregnancies were studied to assess the accuracy of GA during the first and second-trimesters. Most QC results in all hospitals were found to be within the baseline levels and the best performance derived formula was found a combination of Biparietal Diameter BPD , Femur Length FL and distance accuracy.

Most late Quaternary eruptions are dated by 14 C measurements on material from close to the volcano that may be contaminated by geologic-sourced infinite-age carbon. Here we show that 14 C ages for the Taupo New Zealand First Millennium eruption are geographically arrayed, with oldest ages closer to the vent.
We present evidence that the older, vent-proximal 14 C ages were biased by magmatic CO 2 degassed from groundwater, and that the Taupo eruption occurred decades to two centuries after CE. Our reinterpretation implies that ages for other proximally-dated, unobserved, eruptions may also be too old.

Subscriber Account active since. TV cancellation season is coming to a close. This was a tumultuous year for TV lovers — “Brooklyn 99” and “Lucifer” were both saved from cancellation by NBC and Amazon respectively, while fans of MTV’s “‘Shadowhunters” are still praying for a last-minute renewal from another network. And don’t even get us started on “Timeless,” whose fans are still waiting with bated breath to find out the show’s future. Some shows remain “on the bubble” for the most of their run, meaning that they may or may not get canceled.
Some scientists are concerned that—if the pyrosomes die en masse—they could create a large “dead zone,” as their decaying bodies suck.
Technical Resources. Agriculture has been similarly targeted closer to home, where amounts of nitrogen in Iowa’s drinking water supplies have increased dramatically throughout the past century. For example, in a U. Geological Survey study, average annual nitrate concentrations in the Des Moines and Cedar Rivers have increased nearly seven times over the last years, from about 0. Since then, nitrate levels have increased to as high as Over the last 20 years, average nitrate levels in the Raccoon River average 7.

When nutrient-rich freshwater creates a layer atop the saltier Gulf waters, nitrogen and phosphorus feed huge algae blooms. When the algae die, they sink into the saltier water below and decompose, using up oxygen to create the dead zone. See infographic below for more details. The U. Environmental Protection Agency has set a goal of reducing nitrogen pollution along the Mississippi River watershed by 45 percent reduction goal, as necessary to reduce the size of the dead zone to less than 1, square miles.
Federal and state officials along the Mississippi and Ohio river watersheds had implemented mostly voluntary measures to control the amount of fertilizer used on crops, and have urged planting “cover” crops to suck up remaining fertilizer during offseasons.
USA to Air Banned Episode of ‘Dead Zone’ will be made to the episode when it airs this summer (the exact date is still to be announced).
The invention pertains to automatic steering control of marine vessels, and more particularly to compensation for steering systems that exhibit dead-zone characteristics. Marine high-speed craft frequently use water jets for combined propulsion and steering. These systems utilize paddles that straddle the water jets. When the paddles are rotated the water streams from the jets are deflected causing the craft to change direction. These devices, however, may exhibit a steering dead-zone.
Helm orders for small angular turns produce small angular rotations of the paddles with a concomitant small or zero deflection of the water stream, which may be insufficient to steer the craft. This creates a major control problem, particularly for an autopilot in a course maintaining mode wherein it is continuously making small course corrections.
The problem is exacerbated for high speed craft, which are especially prone to instability in maintaining heading due to the dead-zone problem. An uncompensated or improperly compensated dead-zone always results in reduced heading keeping accuracy, longer and less fuel efficient voyages, and a less comfortable ride for passengers and crew.

The waters off Oregon’s coast experienced low-oxygen conditions for the eighth consecutive year in , Oregon State University researchers said Thursday, an indication that late summer “hypoxic” conditions that can kill crabs and other sea creatures near the ocean floor are here to stay. I would expect hypoxia to show up to some degree every year now. The increase in persistent, strong winds and in ocean surface temperatures that are helping drive the phenomenon are consistent with changes predicted by climate change models, Barth said, meaning the problem could worsen if global warming projections pan out.
This summer, the winds that fuel annual upwelling died down in August and September, when oxygen levels are usually lowest. That allowed Oregon to avoid the severe hypoxia and significant biological “dead zones” that appeared in force in , OSU researchers said. But it was a close call in some spots: In early August, the oxygen level got as low as 0. Crabs, anemones, sea stars, sea cucumbers and other creatures can die off when oxygen levels get too low.
The hypoxia area near the ocean floor, stretching from Oregon into Washington, was about average in size and duration in comparison with recent years, the researchers said. It was less severe than , when strong and steady winds led to zero-oxygen, or “anoxic” conditions, and caused alarming die-offs of crabs and other creatures, Barth said.
The low-oxygen areas are typically labeled “dead zones.

Walken debuted as a film director and screenwriter with the short film Popcorn Shrimp. He also wrote and played the lead role in the play Him about his idol Elvis Presley. He was raised Methodist. Then I saw him on television.
I loved everything about him. As a child, Walken appeared on screen as an extra in numerous anthology series and variety shows during the Golden Age of Television. During this time, he was credited as Ronnie Walken. Over the next two years, he appeared frequently on television landing a role in the experimental film Me and My Brother and had a thriving career in theatre. In , he changed his first name to Christopher at the suggestion of Monique van Vooren , who had a nightclub act in which Walken was a dancer and who believed the name suited him better than Ronnie a pet form of his given name, Ronald , which he was credited as until then.
