Title: Effects of nuclear detonations on the ionosphere Corporate Source: Publication Date: Evans Signal Lab., 22 May 1957 Report Number(s): AD-361772 Document Type: Report Language: English Journal Announcement: p 75 Belmar, NJ ‘ (USA) EDB8107 Availability: NTIS, PC A04/MF A0l. Subfile: ERA (Energy Research Abstracts); NTS (NTIS). Country of Origin: United States Country of Publication: United States Abstract: During Operation CASTLE, two ionosphere recorders were operated in the- Marshall Islands -at Site Elmer, about 200 miles west of Bikini Atoll, and at Rongerik Atoll, about 150 miles east of Bikini -- in order to study the effects of the detonations on the ionosphere. Severe absorption was observed 200 miles west of all multimegaton shots, lasting several hours, presumably due to ionization caused by radioactive material carried by high-level winds. Turbulence in the E region after each major shot was indicated by the diffuse sporadic-E returns at Rongerik. Ionospheric disturbances were found up to 2,600 miles away, with indicated velocities of about 8 to 16 km/min.; Major Descriptors: *CASTLE PROJECT; *E REGION -- DISTURBANCES Descriptors: IONOSPHERE; NUCLEAR EXPLOSIONS; Broader Terms: EARTH ATMOSPHERE; EXPLOSIONS; ; PLANETARY IONOSPHERES RADIOACTIVITY IONOSPHERE; NUCLEAR EXPLOSIONS Subject Categories: 640202* -- Atmospheric Physics -- Effects of Nuclear Detonations 450200 -- Military Technology, Weaponry, & National Defense -- Nuclear Explosions & Explosives 10/5/740 (Item 440 from file: 103) 00876650 ERA-07-023550; EDB-82-051491 Title: Circulation in Enewetak Atoll lagoon Author(s): Atkinson, M.; Smith, S.V.; Affiliation: Univ. of Hawaii, Kaneohe Stroup, Source: Limnol.

Coden: LIOCA» EHY-77-S-08-1529 Document Type: Journal Article Language: English Journal Announcement: Subfile: ERA EDB8202 (Energy Research Abstracts); Country of Origin: United States Abstract: Currents at Enewetak Atoll, SAI Marshall (Science Applications Inc.) Islands, were measured on the reef margins, in the channels, and in the lagoon. Lagoon CO circulation is dominated by wind-driven downwind surface flow and an upwind middepth return flow. This wind-driven flow has the characteristics of an Ekman spiral in an enclosed sea. Lagoon flushing o is accomplished primarily by surf-driven water input over the windward “° (eastern) reefs and southerly drift out the South Channel. Mean water residence time is 1 month, while water entering the northern portion off, the atoll takes about 4 months to exit.; Major Descriptors: *ENIWETOK -- WATER CURRENTS
