TL;DR: Korotnevella species can be divided into three groups on the basis of scale morphology, suggesting that the genus may not be monophyletic, and two new species are described from mesohaline ecosystems.
Abstract: Two new species of Korotnevella Goodkov, 1988, Korotnevella hemistylolepis n. sp. and Korotnevella monacantholepis n. sp., are described from mesohaline ecosystems. The amoebae are characterized on the basis of light and electron microscopy with special emphasis on the structure of the basket scales, which have species-specific architecture. The two new species are the second and third ones recovered from environments other than freshwater. In terms of scale morphology they most closely resemble a freshwater species, Korotnevella bulla (Schaeffer, 1926) Goodkov, 1988. Two genus names, Dactylamoeba Korotnev, 1880 and Korotnevella Goodkov, 1988, are in current use. The latter name is preferred, pending rediscovery and characterization of Dactylamoeba elongata Korotnev, 1880, the type species of the genus. Korotnevella species can be divided into three groups on the basis of scale morphology, suggesting that the genus may not be monophyletic. A key to species is provided.

TL;DR: In this article, the authors compare along-track gravity and gridded gravity fields derived from ERS-1 fast delivery altimeter data to those computed from Geosat Geodetic Mission altimeter observations in the Southern Ocean.
Abstract: To estimate how well ERS-1 data from the 35-day repeat mission can resolve fine structure in the marine geoid or gravity field, we compare along-track gravity and gridded gravity fields derived from ERS-1 fast delivery altimeter data to those computed from Geosat Geodetic Mission altimeter observations in the Southern Ocean. We find that single passes of ERS-1 data can resolve along-track gravity anomalies with wavelengths as short as 28–30 km (i.e., comparable to Geosat). However, the ERS-1 gridded gravity field can only resolve anomalies as short as 66 km (versus ∼18 km for Geosat). This two-dimensional resolution is limited by the larger ground track spacing (∼35 km at 60° S) of ERS-1. To resolve fine structure in the marine gravity field it is essential to have altimeter data along more closely-spaced ground tracks, such as those planned for the ERS-1 176-day repeat mission in 1994.
