Marine scientists monitor longest mammal migration

12.04.2007
So you think you have a long commute?

Marine scientists recently published a research paper in the science journal, biology letters, that found humpback whales migrate over 5,100 miles from Central America to their feeding grounds off Antarctica; a record distance undertaken by any mammal.

Kristin Rasmussen, a biologist with Cascadia Research Collective, and lead author in the study, finds the record-breaking migration interesting, but is most pleased that the study validates a long held assumption that humpback whales travel to warm water areas during the winter.

"It was very exciting because for years everyone said humpback whales could be found in warmer waters during the winter months, but this was the first time we were actually able to quantify this on a global scale, and relate it to these long distance migrations" said Rasmussen.

Researchers conducted the survey by identifying individual humpback whales on their wintering area off Central America, and then comparing these with whales identified on their feeding areas off Antarctica. Identification of individual whales is accomplished by comparing a unique set of markings on their fluke, like a "fingerprint," with a catalog of photographs held by the Antarctic Humpback Whale Catalog at the College of the Atlantic in Bar Harbor, Maine.

The scientists found some humpbacks traveling from Antarctica across the equator to as far north as Costa Rica to overwinter, a distance of approximately 8,300 kilometers or about 5,157 miles. The authors noticed that the presence of cold water along the equator coincided with the occurrence of this northerly wintering area, not only in the eastern Pacific, where the Central American whales were studied, but also in the eastern Atlantic, where another southern hemisphere humpback whale population can be found north of the equator during winter.

Daniel Palacios, an oceanographer working out of NOAA’s Southwest Fisheries Science Center laboratory in Pacific Grove, Calif., correlated sea-surface temperature with the whale migration by using data collected from satellites and distributed by the National Oceanographic Data Center.

"This study was possible thanks to the availability of reliable, high-resolution sea-surface temperature data collection that cover even the most remote regions of the globe," said Palacios.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
