Seismic measurements of explosions in the Tatum Salt Dome, Mississippi

Project Sterling provided for the detonation of a nuclear device in the cavity resulting from the Salmon nuclear explosion in the Tatum salt dome in southern Mississippi. It also provided for a high explosive (HE) comparison shot in a nearby drill hole. The purpose of the experiment was to gather information on the seismic decoupling of a nuclear explosion in a cavity by comparing seismic signals from a nuclear shot in the Salmon cavity with seismic signals recorded from Salmon and with seismic signals recorded from a muall (about 2 tons) HE shot in the salt dome. Surface seismic measurements were made by the U.S. Geological Survey, the U.S. Coast and Geodetic Survey, and the Air Force Technical Applications Center with coordination and overall direction by the Lawrence Radiation Laboratory. This report covers only the seismic measurements made by the U. S. Geological Survey. The first objective of this report is to describe the field recording procedures and the data obtained by the U. S. Geological Survey from these events. The second objective is to describe the spectral analyses which have been made on the data and the relative seismic amplitudes which have been determined from these analyses.

Band loss by nestling mourning doves

Nestling mourning doves ( Zenaidura macroura ) were banded and checked for band loss prior to fledging at Parchman, Mississippi, during the months of June-August, 1960. Three hundred seventy-seven nestlings 4-6 days of age were banded, 117 with size 3 bands, 120 with size 3A bands, and 140 with size 3A bands secured by Dalzoflex tape. Two hundred twenty nestlings 7-9 days of age were banded, 114 with size 3 bands and 106 with size 3A bands. In the 4- to 6-day age group, 66.3 percent of the size 3A bands were lost. This was a statistically significant departure from the 7.7 percent loss of size 3 bands. No taped bands were lost. However, predators ate 13.8 percent of the nestlings with taped bands and significantly fewer of the nestlings banded without tape. In the 4- to 6-day age group, percentages of nestlings known to be available for band recovery at 9 days or older were: size 3, 69.2 percent; size 3A with tape, 59.0 percent; size 3A, 25.8 percent. In the 7-to 9-day age group, there was a 3.3 percent loss of size 3A bands and no loss of size 3 bands. The minimum age at which nestlings were banded without subsequent loss of bands was 6 days for size 3 and 8 days for size 3A.

Irrigation in northeastern Mississippi

The phenomenal increase in the use of water for agriculture, industry, and public water supply in the past few years has been an important factor in bringing about the current accelerated inventory and appraisal of the water resources of Mississippi. As a result of severe droughts during the past several years, and of the favorable results of experiments, the water resources of northeastern Mississippi today are rapidly being developed for irrigation. Records have shown that even during years of normal rainfall the distribution of the rain usually is such that supplementary irrigation can be profitably practiced on almost any crop. Although in northeaster Mississippi the annual precipitation generally is enough to support crops and pasture, short periods of drought are common. Supplemental irrigation protects against the periods of drought during the growing season and increases the yield and quality of crops.

Flood of May 27-28, 1954, in Panola and Lafayette Counties, Mississippi

As a result of heavy rains during the late afternoon and night of May 27, 1954, record-breaking floods occurred on small streams in Panola and Lafayette Counties. All flooding was in rural areas, and no loss of life was reported. The Agriculture Stabilization Committees at Sardis and at Oxford estimated the crop and soil losses in Panola county as $400,000, and in Lafayette County as $25,000. The total damage to county roads and State highways was estimated to be in excess of $25,000. The purpose of this report is to present rainfall information and more detailed runoff data than are found in the regular Water Supply Papers. The report contains a summary of peak discharges at 10 miscellaneous sites and a detailed record of discharge at the gaging station Clear Creek near Oxford, Miss. Field investigation incident to this report were conducted by members of the District Office, U.S. Geological Survey, Jackson, Miss., I. E. Anderson, District Engineer.

Flood of August 1953 in the vicinity of Tylertown, Mississippi

The United States Geological Survey in cooperation with the Mississippi Highway Department has been studying the surface-water resources and problems of Mississippi as they affect the highway program. One phase of this program is the determination of flood runoff from small drainage areas. This is the final of two reports on the August 1953 flood; the first or preliminary report was released to the Highway Department as an administrative report in November 1953.
