The Truth About Soviet Whaling: A Memoir

In November 1993, Professor Alexei Yablokov, who at the time was the Science Advisor to Russian President Boris Yeltsin, stood on a podium in Galveston, Tex., and delivered a speech to the Society for Marine Mammalogy’s biennial conference, the premier international event in the field of marine mammal science. Addressing the 1,500 scientists present, he made what amounted to a national confession: that, beginning in 1948, the U.S.S.R. had begun a huge campaign of illegal whaling. Despite being a signatory to the International Convention on the Regulation of Whaling (signed in Washington, D.C., just 2 years before in 1946), the Soviets set out to pillage the world’s ocean

The Truth About Soviet Whaling

I have always condemned (and to do anything more was not within our power or abilities) the illegal and sometimes destructive whaling by the Soviet Union. This opinion was expressed in numerous documents, including reports and records of presentations at scientific and other meetings; these documents are the witnesses to this condemnation. However, none of these documents ever saw the light of day: all of them were marked with the sinister stamp “secret.” When necessary in this memoir, my opinion of the whaling will be supported by data drawn from these docume

Dynamic condition monitoring of buried gas pipes

This paper describes a device which can be used to detect variation in the integrity of the surrounding medium which supports buried gas pipes. The method is also applicable to other kinds of pipe. Variation in pipe support condition leads to increased likelihood of pipe damage under vehicle loading. A vibrating 'pig' has been developed and tested on buried pipelines in Britain and the measured data obtained is compared with theoretical models. Certain features, such as voids, hard spots and joints, display characteristic responses to vibration and a library of such characteristics has been constructed both experimentally and from the theoretical models.

Identification of support conditions of buried pipes using a vibrating pig

This paper describes a method for monitoring the variation in support condition of pipelines using a vibration technique. The method is useful for detecting poor support of buried pipelines and for detecting spanning and depth of cover in sub-sea lines. Variation in the pipe support condition leads to increased likelihood of pipe damage. Under roadways, poorly supported pipe may be damaged by vehicle loading. At sea, spanned sections of pipe are vulnerable to ocean current loading and also to snagging by stray anchors in shallow waters. A vibrating `pig' has been developed and tested on buried pipelines. Certain features of pipe support, such as voids and hard spots, display characteristic responses to vibration, and these are measured by the vibrating pig. Post-processing of the measured vibration data is used to produce a graphical representation of the pipeline support and certain `feature characteristics' are identified. In field tests on a pipeline with deliberately constructed support faults, features detected by the vibrating pig are in good agreement with the known construction.
