Voyager 1 and Voyager 2 are about to pierce the heleosphere, which protects our solar system from cosmic radiation, and enter interstellar space. The probes have already collected a wealth of data about our solar system, and they’re now collecting data about the edge of our solar system and soon, they’ll collect data about what lies beyond our solar system.
In addition to collecting information about our solar system and what lies beyond, each probe also contains a special record that contains information about our planet and humanity. Via NASA:
Each probe is famously equipped with a Golden Record, literally, a gold-coated copper phonograph record. It contains 118 photographs of Earth; 90 minutes of the world’s greatest music; an audio essay entitled Sounds of Earth (featuring everything from burbling mud pots to barking dogs to a roaring Saturn 5 liftoff); greetings in 55 human languages and one whale language; the brain waves of a young woman in love; and salutations from the Secretary General of the United Nations. A team led by Carl Sagan assembled the record as a message to possible extraterrestrial civilizations that might encounter the spacecraft.
“A billion years from now, when everything on Earth we’ve ever made has crumbled into dust, when the continents have changed beyond recognition and our species is unimaginably altered or extinct, the Voyager record will speak for us,” wrote Carl Sagan and Ann Druyan in an introduction to a CD version of the record.
Despite a looming government shutdown, Republicans are still using the budget bill process to impose right-wing policies on all Americans by inserting policy riders that have no place in a budget bill. These policy riders have included riders to defund healthcare reform, defund NPR, defund PBS, cut spending for Planned Parenthood, and cut spending to the Environmental Protection Agency, thereby attacking healthcare reform, women’s health, clean air, and clean water. Furthermore, these policy riders attack domestic discretionary spending that has nothing to do with avoiding a government shutdown or reducing the national deficit or the national debt and could actually result in more debt and put Americans at risk. Republican shenanigans to force a government shutdown could also hurt economic recovery. Undoubtedly, the spending cuts are more ideological in nature and have nothing to do with passing a budget or keeping the U.S. government running. Most recently, Tea Party members actually cheered for a government shutdown (and it appears that a majority of Republicans actually favor a government shutdown over a budget compromise), but a government shutdown would actually cost taxpayers money. According to U.S. Senator Jack Reed, “The Gingrich-led government shutdowns of 1995 and 1996 lasted 26 days and cost taxpayers over $1.4 billion.”
A dog rescued from the sea atop the floating debris of a house has been re-united with her owner, three weeks after the March 11 earthquake and tsunami that devastated northeastern Japan.
Images on Japan’s NHK TV showed the medium-sized brown dog, named “Ban,” wagging her tail in the arms of her owner Monday at an animal shelter in the quake-battered region of Miyagi.
Ban was plucked off the wreckage of a house drifting almost two kilometers off the shore last week by a Japanese helicopter rescue crew.
The dog’s owner, whose name was not made public, saw the rescue on television and rushed to claim her pet.
Thousands of people are still missing three weeks after the disaster, which left more than 12,000 dead and orphaned dozens of pets.
In a fishery, which can mean many things, fishers target certain species for personal consumption or for market. However, sometimes, fishers catch other species in addition to the species that they’re targeting. These non-target species are known as bycatch, and even though bycatch might be illegal to keep, to consume, to target, or to market, bycatch may still be incidentally caught in some fisheries.
Therefore, if the fisher doesn’t have a permit to keep certain species or if the species is illegal to keep, it’s simply wastefully discarded overboard. Bycatch isn’t wasted, however, if a fisheries observer is onboard to scientifically sample the species or if the fishers keep the specimen to turnover to scientists for research. As a result, bycatch can yield valuable data about a species and its interaction with commercial fishing gear.
Due to being incidentally caught, some species, in particular, are at risk. For example, populations of endangered species, valuable species, or species that are easily caught as bycatch in certain fisheries suffer from illegal fishing or from fisheries that are inefficient or dirty. However, fisheries research can result in improvements that mitigate or even eliminate bycatch of certain species (thus making the fishery cleaner), so cooperative research is important in ensuring continued seafood production and in making fisheries more sustainable.
Directed fishing for bluefin tuna in the Gulf has been prohibited since the early 1980s, however bluefin are caught incidentally by longline fishermen who target other species. The Gulf of Mexico is the only known spawning area for the western stock of Atlantic bluefin tuna, a historically overfished species. Many bluefin die from the stress endured in this incidental capture in warm water even if fishermen release them.
“NOAA worked with longline fishermen from the Gulf to test the weak hook carefully over the last three years,” said Eric Schwaab, assistant NOAA administrator for NOAA’s Fisheries Service. “Our cooperative scientific research with fishermen is showing that this new technology can protect bluefin tuna in the Gulf while still allowing fishermen to target yellowfin tuna and swordfish.”
The weak hook is a circular hook constructed of thin gauge wire, and is designed to straighten when a large fish, such as bluefin tuna, is hooked, releasing it but holding on to smaller fish. The average size of bluefin tuna landed in the Gulf of Mexico longline fishery is 485 pounds, while the average for yellowfin tuna is about 86 pounds.
Yellowfin tuna and swordfish are valuable commercial fisheries in the Gulf of Mexico, supporting fishing jobs on approximately 50 vessels as well as jobs on shore. The two species bring longline fishermen annual dockside earnings of $7 million. Research showed that the weak hook could result in some reductions in target catch while some longline fishermen have reported weak hooks did not hurt their businesses.
“During our tests, we used regular hooks for half our hooks and half were the new weak hooks,” said Capt. Mike Carden, a longline fisherman from Panama City, Fla. who took part in the cooperative research. “We were so happy with the weak hooks we quit using the heavy hooks. The weak hook releases fish we don’t want to catch. Because it’s smaller and lighter, we catch more yellowfin tuna on the weak hook. There’s several of us who have gone to the weak hook.”
The agency release included a supporting comment from a captain of one of the 50 or so commercial longline vessels in the fishery:
“During our tests, we used regular hooks for half our hooks and half were the new weak hooks,” said Capt. Mike Carden, a longline fisherman from Panama City, Fla., who took part in the cooperative research. “We were so happy with the weak hooks we quit using the heavy hooks. The weak hook releases fish we don’t want to catch. Because it’s smaller and lighter, we catch more yellowfin tuna on the weak hook. There’s several of us who have gone to the weak hook.”
The Pew Environmental Trusts, which has been tracking the issue closely, gave a very mixed review to the move. Here’s a statement e-mailed to me by Dave Bard, a spokesman, followed by a video the group has produced on bluefin and the gulf:
Pew is pleased that the National Marine Fisheries Service (NMFS) has recognized the major bycatch problem with bluefin tuna in the Gulf of Mexico, the fish’s only known spawning area in the western Atlantic Ocean. The agency has issued a short-term solution requiring the use of “weak” hooks starting May 5, 2011. Pew is also pleased that NMFS has left the door open to consider long-term solutions including time and area closures. But, a year-round prohibition on surface longlines is the only way to provide effective long-term protection for bluefin tuna and other rare and beautiful species in the Gulf. This prohibition would still allow fishermen in the Gulf to catch swordfish and yellowfin tuna; they would just be required to use more selective alternatives to wasteful surface longlines.
