Can I dive without a BCD?

How can I dive without a BCD? An essential ability of the vintage diver is to dive without a buoyancy compensation device. This is accomplished by weighting the diver properly, and diving the right tanks. Vintage tanks are primarily smaller volumes that their modern counterparts, usually 50 or 72 cubic feet. This means that the amount of "swing" exhibited by breathing in the contents of the cylinder are a lot less than on a modern high pressure 100 cubic foot cylinder. A steel low pressure 72 cubic foot tank, for example, swings about 4 pounds from full to empty. This means that the diver can simply weight himself for the buoyancy of his wet suit, and compensate for the 4 pound swing of gas with his lungs. Another technique is to "split the difference". If the diver knows that a steel 72 is 4 pounds negative when full and basically neutral when empty, then he can count the tank as being 2 pounds negative (the split of the difference between full and empty). This means that if his wetsuit needs 5 pounds of lead to be neutral, then he wears 3 pounds and counts the tank's median buoyancy as the other 2 pounds. The average human can easily manage 4 pounds of negative or positive buoyancy (the layman's kind of buoyancy) by controlling their breathing. Simply put, vintage divers can hover, ascend, descend, and stop at will just like modern divers using a few techniques, a little math, and some common sense.

Feds Extend Own Deadline for Deciding on Hawaiian Monk Seal Critical Habitat

HONOLULU— The National Marine Fisheries Service announced today that it needs
six more months to decide how much habitat to protect for critically endangered
Hawaiian
monk seals. In response to a 2008 petition from three conservation groups,
the agency is considering a proposal to protect 11,000 square miles of coastal
areas in the main Hawaiian Islands as critical habitat for the seals. Hawaiian
monk seals are among the most endangered marine mammals in the world, with a
population of approximately 1,100 animals.

Study: The U.S. could be powered by 80% green energy in 2050

According to a study published by the National Renewable Energy Laboratory (NREL), up to 80% of the power needed by the whole country could be supplied by renewable energy sources by 2050. The agency even believes that a large chunk of that — 50%, in fact — could come from wind and solar energy sources, which are sometimes criticized due to their unpredictable output.
