Gulf of Mexico Bio-social Ecosystems are Under Assault

This is the 53rd day that the muck is floating in the Gulf of Mexico killing every organic creature within reach and destroying every viable economic structure within the region. British Petroleum invaded the shores of southern US, with crude oil gushing up the ocean floor with no apparent defense and protection from the US [...]

Gulf Oil Spill – Blame-Shifting

So now the companies involved in the exploded oil rig in the Gulf of Mexico are finger-pointing at each other. Shifting blames is the call. Shame  on you BP and friends. Quit complaining and do whatever is needed to stop the leak, to stop the continuous gush of millions of gallons of crude oil into [...]

House Relocating – Bio-Social Networking In Hermit Crabs

A recent study in New England described a process in hermit crab populations by which individuals of different body size use a simple social networking system to find new housing. Hermit crabs, which are decapod (ten-legged) crustaceans common in the intertidal zone and in fresh water ponds, have soft abdomens. To protect themselves from predators [...]

Ocean Oil Spills – Human Persistence

Talks about keeping the seas clean from oil muck are one thing, while action to prevent oil spills is another. Last week’s big-time oil spill in the Gulf of Mexico was not just another wrecked tanker: this time the oil is shooting up from the ocean’s depth via a man-made well to the water’s upper [...]

Navigating Downwind

A Study published in last week’s Science showed a remarkable ability of migratory butterflies and moths flying several hundreds of meters above the ground to successfully undertake long-distance journeys to their destinations. These insects have a compass sense that enable them to select winds which will take them in their chosen direction, at speeds of [...]

Would Whales Be Forced Out From The Pacific Northwest Waters?

Recently studies have indicated that carbon dioxide absorption by the seas not only warms and acidifies the oceans but it also affects acoustical properties of seawater, making it more transparent to low-frequency sound. It was found that lower seawater pH lowers seawater sound absorption. As the ocean waters become more acidic over time the low-frequencies [...]

Global Warming – Save The Planet – Copenhagen Meeting

During December 7-18, 2009 world leaders and policy makers will gather in Copenhagen, Denmark to discuss ways to save the deteriorating ecological viability of our planet ignited by the inability to control global warming and other human destructive activities. My take on this is: Corporations and governments need to devise commitments to policies and treaties [...]

New Baby Orca – Salish Sea

Great news ! A newborn orca whale has been spotted a couple of days ago in the Salish Sea waters near Victoria, BC. The baby whale was designated as J-46. The Orca Network believes that the mother is the 16 year-old J-28.
Cheers to the Salish Sea killer whale population.

Marbled Murrelet slow decline along the Olympic Coast

The marbled murrelet population along Washington Pacific coast is slowly decreasing in numbers. This tiny alcid seabird spends its entire life at sea, coming briefly inland to nest in old-growth and mature coniferous forests where it raises only one chick. The marbled murrelet is losing its ability to sustain a viable population size along the coastal [...]

Killer whales in the Salish Sea

Recent data indicate that the numbers of resident roaming the Salish Sea waters of Washington are diminishing at about 20%. The reasons for this decline are basically unknown. But experts are presuming that reduction in fish populations, water pollution and toxins, vessel traffic and noise are to blame for the orca recent low numbers. With the killer whale being on [...]
