Full Fathom 5000


Book Description

"The abyssal plain. If you could walk directly into the sea, through the surf and away from the land, you would be likely to descend a gentle slope for two or three days. The water over your head would gradually become deeper, until the surface was about 200m above, say two average city blocks away. About this time the gradient would begin to increase, and soon you are walking quite steeply downhill, with the surface rapidly receding. The sediment beneath your feet will thicken as you approach the edge of the continent, where the soil and debris washed from the land eventually accumulates. At the end of a long day's walk the gradient eases and you stride out onto a prairie that stretches away into the far distance, flat and featureless, or sometimes with rolling hills or even studded with sudden abrupt mountains. The surface is now quite far away, not mere city blocks but the whole downtown core of a large city distant from where you stand. You have arrived at the edge of the abyssal plain. The details of your walk will vary according to where you start out, and might be quite different if you begin in eastern Canada and walk into the Atlantic, say, or in western Canada and walk into the North Pacific. In either case, though, you will eventually reach the abyssal plain, where the last of the land has been left behind and nothing is familiar"--













At Sea with the Scientifics


Book Description

When HMS Challenger sailed from Portsmouth in 1872, a young assistant ship's steward, Joseph Matkin, was among the crew. Throughout the three-and-a-half-year voyage, Matkin maintained a journal from which he composed the many letters he sent home to his family in England. In his letters he commented on oceanographic operations, reported on shipboard events of special concern to the crew, and discussed at length the history, geography, and peoples of the many exotic and remote ports at which the ship called on its famous circumnavigation of the globe. The Challenger expedition established the foundations of oceanography and is second only to Darwin's voyage aboard the Beagle for its contributions to nineteenth-century science. The massive quantity of specimens and information acquired was written up in the fity-volume series of Challenger Reports, and personal accounts were published by officers and scientists. No ocean voyage had ever been so well documented. Yet no account of the seaman's life "below decks" was known to exist until the early 1980s, when two substantial collections of Matkin's letters surfaced. The letters are unique in their perspective and fascinating for their depth and literacy. Matkin, the son of a printer, was well aware of the significance of the voyage and strove to present a learned account in a proper style. His letters convey a wealth of detail about shipboard logistics, the crew's attitudes toward scientific operations, and officer-scientist-crew relations. Unwittingly, Matkin also illuminates himself and the middle-class society of which he was a part. Matkin's letters, published here for the first time, bring freshness and immediacy to this great Victorian scientific enterprise. Philip F. Rehbock has edited and annotated the letters, providing a particularly readable work of travel literature for anyone interested in oceanography, voyaging, maritime social history, and naval affairs.




Scientists and the Sea, 1650–1900


Book Description

Scientists and the Sea is a history of how the scientific study of the sea has developed over a period of nearly 2500 years. Beginning with the speculations of Greek philosophers it carries the story forward, showing how curiosity about the ocean appeared in many different forms and locations before, in the late 19th century, the first deep-sea researches heralded the foundation of the science known today as oceanography. Originally published in 1971, this book has never been superseded as the most comprehensive and wide-ranging treatment of the emergence of marine science within the western scientific tradition. After three introductory chapters dealing with knowledge up to the Renaissance, the main part of the work shows how pioneers of scientific observation at sea during the 17th and 18th centuries made notable discoveries, but that it was not until the middle of the 19th century when, aided by the advance of technology, scientists were able to undertake the first explorations of the ocean depths. This second edition contains a new introduction and bibliography.







Pleistoannelida, Sedentaria II


Book Description

This book is the second volume in a series of 4 volumes in the Handbook of Zoology series treating morphology, anatomy, reproduction, development, ecology, phylogeny, systematics and taxonomy of polychaetous Annelida. In this volume a comprehensive review of a few more derived higher taxa within Sedentaria are given, namely Sabellida, Opheliida/Capitellida as well as Hrabeiellidae. The former comprise annelids possessing a body divided into two more or less distinct regions or tagmata called thorax and abdomen. Here two groups of families are united, the spioniform and sabelliform polychaetes. Especially Spionidae and Sabellidae are speciose families within this group and represent two of the largest annelid families. These animals live in various types of burrows or tubes and all possess so-called feeding palps. In one group these appendages are differentiated as grooved feeding palps, whereas in the other they may form highly elaborated circular tentacular crowns comprising a number of radioles mostly giving off numerous filamentous pinnulae. Often additionally colourful, the latter are also received the common names "feather-duster worms", "flowers of the sea", "Christmas-tree worms". Opheliida/Capitellida including five families of truly worm-like annelids without appendages represents the contrary. Their members burrow in soft bottom substrates and may be classified as non-selective deposit feeders. Molecular phylogenetic analyses have shown that Echiura or spoon worms, formerly regarded to represent a separate phylum, are members of this group. Last not least Hrabeiellidae is one out of only two families of oligochaete-like terrestrial polychaetes and for this reason received strong scientific interest.
