Re: Blue whales are acting strange in the Pacific, according to a marine biologist. A buddy of mine is a marine biologist, and he says they are diving deeper than ever. So deep, in fact, that it is rewriting the their idea about how deep they can dive. Unlike many other whale species, the Right whale has blowholes spaced far apart, which makes the animals easy to spot from above the surface. As they exhale, a “V” shaped blow pattern can be seen. Smaller than Blue Whales but larger than Grey Whales or Humpback Whales, they grow to be about 18 meters long and can weigh more than 90 tons.
Most whaling nations used to concentrate their hunting efforts to the Antarctic, as whales tend to prefer the colder water. This was banned in as an estimated , blue whales had been killed in the region. Although the news is great for the California Blue whales there is still a long way to go for the rest of the world’s whale levels. Divers will travel far and wide to find the best diving. But those who live in the United States have plenty of great diving on their doorstep as well, with plentiful access to the Atlantic Ocean, the Pacific Ocean and the Gulf of Mexico. From warm-water reefs to temperate seas, here are some of the top places to scuba dive in the United States.
These included establishing the geographic range and migratory patterns of eastern north Pacific blue whales; establishing that the eastern tropical Pacific appears to be a blue whale “hot spot” where as many as four, but primarily three, acoustic populations of blue whales occur; determining that the Gulf of Alaska is a region where Cited by: 1. They eat kg of food per day and are known to take mackerel, salmon, tuna, squid, sea turtles, stingrays, sharks, seals, sea lions, porpoises, dolphins, grey whales, minke whales, and many other species. However, killer whales in the Northeast Pacific Ocean have very specialized diets and do not feed on all prey that are available to them.

Dive characteristics of Northeast Pacific blue whales (Balaenoptera musculus) monitored by satellite telemetry. Seasonal abundance, distribution, and population characteristics of blue whales reported in the to catch records of two Alaska whaling stations. Dive habits of four Northeast Pacific blue whales (Balaenoptera musculus) were studied using satellite-monitored radio tags.
Tags summarized dive-duration data into eight 3-h periods daily. The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whale suborder Mysticeti.
Reaching a maximum confirmed length of meters (98 feet) and weight of tonnes ( tons), it is the largest animal known to have ever existed. The blue whale’s long and slender body can be various shades of grayish-blue dorsally and somewhat lighter : Mammalia. In the North Pacific, acoustic analysis of blue whale vocalizations indicates that there are two populations.
The best known is that from the eastern North Pacific where blue whales reach as far north as Alaska but are regularly observed from California in summer, south to. The Blue Whale is an amazing book and what makes it special is the captivating blending of scientific facts with a sensitive and warm presentation, leading to an immediate interest of readers in the life of blue whales, magnificent and intelligent creatures how Jenni Desmond calls them/5.
The pilot searches for Blue Whales for 3 to 4 hours in an area 15 to 25 miles offshore between San Diego and Mexico. We leave by boat each morning towards the area being scouted. While waiting for the scouting report, if we come across an encounter with other marine life along the way, we will free dive in the lovely blue Pacific.
The first edition of Whelks to Whales has been our go-to reference for all the strange and colorful creatures we find in tide pools. We usually bring it with us on our expeditions and look at it as soon as possible. The second edition is larger by more than 80 pages/5.
Although not noted for raising their flukes when diving, approximately 18% of blue whales observed in the western North Atlantic and Northeast Pacific do so. This is an individual characteristic, and if the individual is relaxed it will generally raise its flukes high up in the air on each sounding by: Blue whales, unlike finbacks, show distinctly different vocalizations in the Atlantic and Pacific; but like finbacks, both Atlantic and Pacific whales have two principal call types, with different.
The minke whale is the second smallest of the baleen whale, and in the north Pacific has been largely under-studied due to its elusive nature. Minke whales can be hard to research; they are fast, observed swimming at speeds of 30 km/h, and their surfacing can been sporadic and hard to follow. Edit: Here are operators that lead free diving trips with Blue Whales (thanks Google) Sri Lanka San.
occurrence of blue whales in the NW Pacific, with the fall–winter period showing the strongest signal. This was surprising because it belied the oft-repeated assumption that all blue whales migrate south in fall to winter, at temperate latitudes, and occupy North Pacific waters only in late spring and summer (e.g., Bowen and Siniff, ).
Colombia Humpback Whales Expedition. Although a few Humpback Whales can be seen as early as May in the Pacific side, t he Whale Watching season in Colombia is from June to October. The best months for whale watching are August and September.
For this reason, we plan to do our dive trips to see the whales in August and September of There is also a very small group of about Western North Pacific Grey Whales that live off the east coast of Asia, and a third population of now extinct grey whales once lived in the northern Atlantic Ocean.
The Nuu-chah-nulth First Nations people once hunted and scavenged grey whales off the coast of Vancouver Island. Although not noted for raising their flukes when diving, approximately 18% of blue whales observed in the western North Atlantic and Northeast Pacific do so.
Studies off Sri Lanka report that 55% of blue whales there fluke up when diving. When feeding at depth, blue whales will generally dive for 8–15 min; min dives are not by: Geographic and seasonal variation of blue whale calls in the North Pacific Kathleen M. Stafford *, Sharon L.

What it's Like To Dive with a Blue Whale The blue whale is as big as it gets; in fact, the biggest animal to ever live on this planet.
You could practice trying to photograph one by taking pictures of boxcars — two or three boxcars in a row. because the blue whale is so big, you wonder why the whales are so hard to find. but they are, and that’s why we’ve created an elaborate blue.
A population of pygmy blue whales (Balaenoptera musculus brevicauda) that inhabits the waters between the North and South islands of New Zealand has been shown to be genetically distinct from other populations around the globe, according to new research.

The text of this book provides an excellent scientific review of what is known about blue whales, particularly off the west coast of North America, where the authors (noted scientists) do their research.
The writing style, despite being scientifically detailed, avoids technical terms and 5/5(3).
