Analysis and geological interpretation of gravity data from GEOS-3 altimeter

A number of detailed gravimetric geoids of portions of the world's oceans from marine gravity measurements were constructed. The geoids were constructed by computing 1 x 1 deg or 10 x 10 deg averages of free-air anomaly data and subtracting these values from currently used satellite derived Earth models. The resulting difference gravity anomalies are then integrated over a sphere using a simplified form of Stoke's equation to obtain a difference geoid. This difference geoid is added to the satellite derived model to obtain a 1 x 1 deg or 10 x 10 deg total gravimetric geoid. The geoid undulations are studied by comparison of the altimeter measurements with the morphology of the ocean floor. Utilizing a combination of altimetry data, gravity and seismic reflection data, geophysical models of the earth can be constructed

Shape of the ocean surface and implications for the Earth's interior: GEOS-3 results

A new set of 1 deg x 1 deg mean free air anomalies was used to construct a gravimetric geoid by Stokes' formula for the Indian Ocean. Utilizing such 1 deg x 1 deg geoid comparisons were made with GEOS-3 radar altimeter estimates of geoid height. Most commonly there were constant offsets and long wavelength discrepancies between the two data sets; there were many probable causes including radial orbit error, scale errors in the geoid, or bias errors in altitude determination. Across the Aleutian Trench the 1 deg x 1 deg gravimetric geoids did not measure the entire depth of the geoid anomaly due to averaging over 1 deg squares and subsequent aliasing of the data. After adjustment of GEOS-3 data to eliminate long wavelength discrepancies, agreement between the altimeter geoid and gravimetric geoid was between 1.7 and 2.7 meters in rms errors. For purposes of geological interpretation, techniques were developed to directly compute the geoid anomaly over models of density within the Earth. In observing the results from satellite altimetry it was possible to identify geoid anomalies over different geologic features in the ocean. Examples and significant results are reported

Petition for a Writ of Certiorari. Lawson v. FMR LLC, 134 S. Ct. 1158 (2014) (No. 12-3), 2012 U.S. S. Ct. Briefs LEXIS 2827

QUESTION PRESENTED Section 806 of the Sarbanes-Oxley Act, 18 U.S.C. § 1514A, forbids a publicly traded company, a mutual fund, or “any ... contractor [or] subcontractor ... of such company [to] ... discriminate against an employee in the terms and conditions of employment because of” certain protected activity. (Emphasis added). The First Circuit held that under section 1514A such contractors and subcontractors, if privately-held, may retaliate against their own employees, and are prohibited only from retaliating against employees of the public companies with which they work. The question presented is: Is an employee of a privately-held contractor or subcontractor of a public company protected from retaliation by section 1514A

Can the South Atlantic Opening Model be Applied to the India Margins?

The presence of SDRs (seawrd dipping reflectors) on the regional lines around the Indian continent strongly suggest the breakup of the lithosphere and the onset of the sea-floor spreading were similar to those proposed and described for the South Atlantic, which, in fact, is quite similar to the opening of the North Atlantic
