In the absence of Magsat quality satellite magnetic field measurements, the use of data of lesser quality is sought. The DE-1 and UARS satellite magnetic field experiments were not designed for the purpose of modeling Earth's main field. The POGS sat

This paper reports on a continuous representation of the main geomagnetic field of degree 13 for the 1900-1995 time period, including a degree 1 representation of the field of external origin, designated GSFC(S95). The model employs a cubic B-spline

Early attempts to model fields from sources in the magnetosphere during magnetically quiet times were unsuccessful. This is attributed to the presence of fields from lithospheric sources and to deficiencies in the data distribution. The availability

The magnetic field from Earth's core (the main field) is a global phenomena with measurable temporal variations with periods ranging from one year to millennia. Geomagnetic studies are thus heavily dependent on the availability of data well distribut

Candidate models were submitted to IAGA Working group V-8 for DGRF 1985 and IGRF 1990. Main field candidates were of degree 10 for each epoch and the 1990 models included secular variation models of degree 8. Two main field candidates for each epoch

All available magnetic data from observatories, satellites, repeat station measurements, and aeromagnetic, shipborne and land surveys are used to derive spherical harmonic models of the geomagnetic field from 1970 to 1990. Two models are derived, one

Some 13 million scalar magnetic field data points that have been collected from the world's ocean areas reside in the collection of the National Geophysical Data Center. In order to derive a suitable data set for modeling the geomagnetic field of the

Life-threatening complications of central venipuncture are rare. We report an unusual case of a patient in whom a large right subclavian pseudoaneurysm developed, causing pressure necrosis of the membranous trachea and esophagus, after right internal

Despite the use of inotropic therapy and the intraaortic balloon pump (IABP), inadequate peripheral organ perfusion and subsequent multiorgan failure from left ventricular dysfunction is a major cause of death following cardiac surgery. To compare th
