Every-day adventurer, Mark Barsdell, is training and working as a geologist in the 1970's when he comes upon opportunities to explore the far reaches of our planet. Through expeditions, field trips and personal adventures, he traverses the most remote regions of Antarctica, the New Hebrides (Vanuatu) and the Arctic, as well as volcanic regions of New Zealand, North America, Mexico and Argentina. Keeping meticulous records of the environments in which he was immersed, his diaries offer a fascinating insight into regions less travelled. Have you ever wondered what it would be like to live on an ice-island, become lost for days on an active volcano, share a tent with an elephant seal or play hopscotch over a pool of hot sulfuric acid? Mark's travels were at a time when true adventure was possible, and through his diaries we can follow his intrepid footsteps.

Challenges and Innovations in Ocean In-Situ Sensors: Measuring Inner Ocean Processes and Health in the Digital Age highlights collaborations of industry and academia in identifying the key challenges and solutions related to ocean observations. A new generation of sensors is presented that addresses the need for higher reliability (e.g. against biofouling), better integration on platforms in terms of size and communication, and data flow across domains (in-situ, space, etc.). Several developments are showcased using a broad diversity of measuring techniques and technologies. Chapters address different sensors and approaches for measurements, including applications, quality monitoring and initiatives that will guide the need for monitoring. Integrates information across key marine and maritime sectors and supports regional policy requirements on monitoring programs Offers tactics for enabling early detection and more effective monitoring of the marine environment and implementation of appropriate management actions Presents new technologies driving the next generation of sensors, allowing readers to understand new capabilities for monitoring and opportunities for another generation of sensors Includes a global vision for ocean monitoring that fosters a new perspective on the direction of ocean measurements

In October, 1984, the Woods Hole Oceanographic Institution SOFAR float group began a three-year long field program to observe the low frequency currents in the Canary Basin. The principal scientific goal was to learn how advection and diffusion by these currents determine the shape and amplitude of the Mediterranean salt tongue. Fourteen floats were launched at a depth of 1100 min a cluster centered on 32N, 24W, and seven other floats were launched incoherently along a north/south line from 24N to 37N. At the same time investigators from Scripps Institution of Oceanography and the University of Rhode Island used four other SOFAR floats to tag a submesoscale lens of Mediterranean water. Slightly over twenty years of float trajectories were p reduced during the first year of the experiment. In this report we briefly describe the 1984 field operations and show the first year's SOFAR float data. Perhaps the most striking result is that westward flow within the Mediterranean salt tongue was found to be confined to a rather narrow jet {roughly 150 km in meridional extent) which had a mean speed of roughly 2 em s -l. To the north or south of this jet the mean flow was much weaker and eastward. This suggests that currents associated with the salt tongue itself {rather than the gyre scale circulation) may be most important for determining the salt distribution.

"To meet the requirements of advancing technologies in the aerospace and other industries, materials are needed with application temperatures higher than those of the nickel-based superalloys currently in use. Intermetallics systems are being considered as candidate materials for advanced high temperature aerospace applications. In particular, the B2 compound NiAl is being extensively studied due to its superior oxidation resistance, high melting point, low density, and high thermal conductivity [1]. However, NiAl is brittle at room temperature and has poor elevated temperature strength, both of which render this material inadequate for structural applications. Reinforcing NiAl with second phases to form composite materials may eliminate these problems. One method for producing NiAl-based composites is by controlling the eutectic solidification process of NiAl based alloys. During eutectic growth, two or more solid phases form simultaneously from the liquid. Directional solidification of these eutectic alloys may produce in-situ composites, where one or more phases are aligned parallel to Ike growth direction. One advantage of producing in-situ composites by directional solidification is that the phases are thermodynamically stable even up to the melting point. A disadvantage is that alloy compositions are limited by the appropriate phase equilibria needed for eutectic growth. Unfortunately, the eutectic compositions for many systems of interest are unknown."--Page 2.
