Chapter 7 100 Years of the Ocean General Circulation
CHAPTER 7 WUNSCH AND FERRARI 7.1 Chapter 7 100 Years of the Ocean General Circulation CARL WUNSCH Massachusetts Institute of Technology, and Harvard University, Cambridge, Massachusetts RAFFAELE FERRARI Massachusetts Institute of Technology, Cambridge, Massachusetts ABSTRACT The central change in understanding of the ocean circulation during the past 100 years has been its emergence as an intensely time-dependent, effectively turbulent and wave-dominated, flow. Early technol- ogies for making the difficult observations were adequate only to depict large-scale, quasi-steady flows. With the electronic revolution of the past 501 years, the emergence of geophysical fluid dynamics, the strongly inhomogeneous time-dependent nature of oceanic circulation physics finally emerged. Mesoscale (balanced), submesoscale oceanic eddies at 100-km horizontal scales and shorter, and internal waves are now known to be central to much of the behavior of the system. Ocean circulation is now recognized to involve both eddies and larger-scale flows with dominant elements and their interactions varying among the classical gyres, the boundary current regions, the Southern Ocean, and the tropics. 1.

A familiar if partially discredited answer would be that Europeans’ guns, steel, ships, alphabetic writing, and perhaps animal dom- esticates, aided and abetted by ‘germs,’ inevitably led them to rule in the Americas and Africa.1 But what if we asked that question with a more suitably generous definition of technology, a definition that would allow for the inclusion of cultivated or even foraged plants as well as prepared foods, one that also allows for communication devices and lit- eracies, auditory and kinesthetic arts like music, dance and prey stalking, and building and furniture technologies such as thatching and hammocks (Figures 1 and 2)? The answers to this question need not nor should not conflict with accounts of (eventual) European and settler-colonial domination, or indigenous adoption of European-originating technol- ogies. -
It Has Often Been Said That Studying the Depths of the Sea Is Like Hovering In
It has often been said that studying the depths of the sea is like hovering in a balloon high above an unknown land which is hidden by clouds, for it is a peculiarity of oceanic research that direct observations of the abyss are impracticable. Instead of the complete picture which vision gives, we have to rely upon a patiently put together mosaic representation of the discoveries made from time to time by sinking instruments and appliances into the deep. (Murray & Hjort, 1912: 22) Figure 1: Portrait of the H.M.S. Challenger. Prologue: Simple Beginnings In 1872, the H.M.S Challenger began its five- year journey that would stretch across every ocean on the planet but the Arctic. Challenger was funded for a single reason; to examine the mysterious workings of the ocean below its surface, previously unexplored. Under steam power, it travelled over 100,000 km and compiled 50 volumes of data and observations on water depth, temperature and conditions, as well as collecting samples of the seafloor, water, and organisms. The devices used to collect this data, while primitive by today’s standards and somewhat imprecise, were effective at giving humanity its first in-depth look into the inner workings of the ocean. By lowering a measured rope attached to a 200 kg weight off the edge of the ship, scientists estimated the depth of the ocean. A single reading could take up to 80 minutes for the weight to reach bottom. Taking a depth measurement also necessitated that the Challenger stop moving, and accurate mapping required a precise knowledge of where the ship was in the world, using navigational tools such as sextants. -

Atlantic History: What and Why?
European Review, Vol. 9, No. 4, 399–411 (2001) Academia Europaea, Printed in the United Kingdom Atlantic history: what and why? NICHOLAS CANNY Department of History, National University of Ireland, Galway, Galway, Ireland. E-mail: [email protected] One of the discernible trends in the historiography of recent decades – especially in that which concerns the early modern centuries – has been the emergence of a literature that describes itself as Atlantic History. This paper seeks to identify positive and negative reasons why the once-popular history of exploration and discovery has given way to this new subject, it identifies some fresh meanings that may be drawn from some well-known sources when they are reappraised in an Atlantic context, and it suggests some possibly fruitful lines of enquiry that would lead to a better understanding of how an Atlantic world was fashioned and functioned during the sixteenth, seventeenth and eighteenth centuries. Finally, the paper draws a distinction between Atlantic history and Global history and suggests that the latter is a subject that belongs more properly to the nineteenth and subsequent centuries. It is relevant to pose the question – Atlantic history: what and why? – because an increasing number of historians, several research centres, and many conferences in both Europe and North America are dedicated to the study of what is being called ‘Atlantic history’. Most scholars involved with these enterprises are specialists of the sixteenth, seventeenth or eighteenth centuries, and all of them are concerned with aspects of exploration, discovery, voluntary and involuntary migration, overseas settlement and trade. If anything unites them it is that, in the words of J. -
Miles Down! Oceanography Through History
MILES DOWN! OCEANOGRAPHY THROUGH HISTORY The history of oceanography is an international story of invention, individual adventure, and exploration that remains little-known. This exhibition presents an historical overview, using timelines, text, photographs, and profiles of oceanographic expeditions and individual scientists from around the world. Image: Colette Kerry From water’s edge, the oceans are as mysterious as the stars. In the 21st century, deep-sea exploration – like space exploration - is no longer a fantastic idea, but a fact of scientific life. How did we move below the surface to study the depths of the sea? This exhibition tells the story of curious humans posing questions about the oceans and developing the tools and technology to move miles down to explore the sea. The oceans that cover 71% of the world’s surface hide complex worlds within their depths. How ocean waters behave, what creatures inhabit the seas, what lies on the ocean floors, what makes up seawater: these are the questions that underlie the scientific study of the oceans - the science of oceanography. Oceanography is the scientific study of the oceans as complex, interrelated systems. It is a mixed science that combines many different approaches to understanding the watery portion of our planet. Physics explores the physical properties of the oceans, the currents and waves. It’s a study of matter and energy and the relation between them. Chemistry is concerned with the properties, composition, and structure of substances in the oceans and the changes they undergo when they combine or react. The geology of the seafloor explores the earth’s history, composition, structure and processes. -

Oxbow lake deposits of the Neris River at the Valakupiai site in Vilnius (Lithuania) have been studied by dif- ferent methods including radiocarbon dating. A timescale was attained for the development of the oxbow lake and climatic events recorded in the sediments. 14C dates obtained for 24 samples cover the range 990–6500 BP (AD 580 to 5600 BC). Medieval human activity was found in the upper part of the sediments. Mollusk fauna found in the basal part of the terrace indicate contact between people living in the Baltic and the Black Sea basins. Mean rates were calculated for erosion of the river and for accumulation during the formation of the first terrace. INTRODUCTION This work presents the results of radiocarbon dating of samples collected at the Valakupiai site, near Vilnius in eastern Lithuania (54°43′58″N, 25°18′33″E; 98.5 m asl) (Figure 1). Special attention was paid to the remnant oxbow lake in the Neris River valley and to the lake-bog deposits filling it. Detailed study of the deposits delivered specific information that enabled paleoecological recon- struction of the site, as well as a description of the geochronological evolution of the oxbow lake and accompanying climatic events. -
