Sports - Diving : Search for the Humboldt Squid

The Humboldt Squid (Dosidicus gigas), also known as Jumbo Squid, Jumbo Flying Squid, or Diablo Rojo (Spanish for Red Devil), is a large, predatory squid found in the waters of the Humboldt Current in the Eastern Pacific Ocean. They are most commonly found at depths of 200–700 metres (660–2,300 ft), from Tierra del Fuego to California. Recent findings suggest the range of this species is spreading north into the waters of Oregon, Washington, British Columbia, and Alaska. Though they usually prefer deep water, between 1,000 and 1,500 squid washed up on the Long Beach Peninsula in southwest Washington in the fall of 2004. They have also ventured into Puget Sound.

Although Humboldt Squid are generally found in the warm Pacific waters off of the Mexican coast, recent years have shown an increase in northern migration. The large 1997-98 El Niño event triggered the first sightings of Humboldt Squid in Monterey Bay. Then, during the minor El Niño event of 2002, Humboldt Squid returned to Monterey Bay in higher numbers and have been seen there year-round since then. Similar trends have been shown off the coasts of Washington, Oregon, and even Alaska, although there are no year-round Humboldt Squid populations in these locations. It has been suggested that this change in migration is due to warming waters during El Niño events, but other factors, such as a decrease in upper trophic level predators that would compete with Humboldt Squid for food, could be impacting the migration shift as well.

Sports - Surfing the Wind @ Mount Washington

Mount Washington is the highest peak in the Northeastern United States at 6,288 ft (1,917 m). It is famous for its dangerously erratic weather, and long held the record for the highest wind gust directly measured at the Earth's surface.

The weather of Mount Washington is notoriously erratic. This is partly due to the convergence of several storm tracks, mainly from the South Atlantic, Gulf region and Pacific Northwest. The vertical rise of the Presidential Range, combined with its north-south orientation, makes it a significant barrier to westerly winds. Low-pressure systems are more favorable to develop along the coastline in the winter months due to the relative temperature differences between the Northeast and the Atlantic Ocean. With these factors combined, winds exceeding hurricane force occur an average of 110 days per year. From November to April, these strong winds are likely to occur during two-thirds of the days.
