When his animal friends offer amusing explanations for thunder and lightning, Franklin overcomes his fear of such storms.

During late March and April 1961, the USCGC EASTWIND (WAGB-279) occupied 30 oceanographic stations in the Indian Ocean. Three sections were made, one running from off Cape Leeuwin, Australia west as far as 78 E. longitude, a second continuing north from this point to 40 N. latitude, and the third which continued west to just south of Socotra Island. Measurements were made of temperature, salinity, and dissolved oxygen; and from these data density, sound velocity, and percentage of saturation of dissolved oxygen were derived. Transparency was determined by Secchi disc, and the Deep Scattering Layer was observed. Continuous recording of bottom depths by echo sounder was carried out through a region where few soundings had hitherto been reported. Northward reaching tongues of Antarctic Intermediate water are shown on the southern profile and on the southnorth profile along the 78 E. meridian. In mid-Indian Ocean, these masses push up toward the surface causing a divergence which is apparent in the salinity and dissolved oxygen profiles. Also delineated are high salinity waters with very low oxygen content which come from the Arabian and Red Seas. The Deep Scattering Layer disappears in mid-Indian Ocean and reappears again to the north, following a similar pattern to that already observed in the Pacific Ocean. (Author).

AG MODULE 1, NAVEDTRA 14269, Surface Weather Observations This module covers the basic procedures that are involved with conducting surface weather observations. It begins with a discussion of surface observation elements, followed by a description of primary and backup observation equipment that is used aboard ships and at shore stations. Module 1 also includes a complete explanation of how to record and encode surface METAR observations using WMO and NAVMETOCCOM guidelines. The module concludes with a description of WMO plotting models and procedures. AG MODULE 2, NAVEDTRA 14270, Miscellaneous Observations and Codes This module concentrates on the observation procedures, equipment, and codes associated with upper-air observations and bathythermograph observations. Module 2 also discusses aviation weather codes, such as TAFs and PIREPs, and includes a chapter on surf observation procedures. Radiological fallout and chemical contamination plotting procedures are also explained. AG MODULE 3, NAVEDTRA 14271, Environmental Satellites and Weather Radar This module describes the various type of environmental satellites, satellite imagery, and associated terminology. It also discusses satellite receiving equipment. In addition, Module 3 contains information on the Weather Surveillance Radar-1988 Doppler (WSR-88D). It includes a discussion of electromagnetic energy and radar propagation theory, and explains the basic principles of Doppler radar. The module also describes the configuration and operation of the WSR-88D, as well as WSR-88D products. AG MODULE 4, NAVEDTRA 14272, Environmental Communications and Administration This module covers several of the most widely used environmental communications systems within the METOC community. It also describes the software programs and products associated with these systems. The module concludes with a discussion of basic administration procedures.
