The Paleontological Society is now accepting applications for two student members to participate in Geo-CVD 2019! The American Geosciences Institute (AGI), in collaboration with other science societies including the Paleontological Society, invites members of the geoscience community from across the nation to come to Washington, DC, for the annual Geoscience Congressional Visits Day (Geo-CVD) on September 10-11, 2019.
upper plane bed . A bed configuration under a unidirectional current that is characterized by a flat, almost featureless surface over which sediment transport is intense, both in suspension and on the bed. Some authors report very low, downstream migrating bed forms as being characteristic of this bed configuration (e.g., Best and Bridge, 1992). Current lineations are common on upper plane bed surfaces. Syn: upper flow regime plane bed; upper stage plane bed.

On 25 June 2019, the House passed the fiscal year (FY) 2020 Interior, Environment, and Related Agencies appropriations bill as part of a five-bill minibus, H.R. 3055. The bill would increase funding for the U.S. Geological Survey (USGS) over FY2019 levels and the Administration’s budget request. The bill also includes report language that prohibits the proposed reorganization and blocks an attempt to relocate staff of the USGS away from the Washington, D.C. area.
catenary ripple . "A ripple is described as catenary if the trace of its crestline has the pattern of a chain of catenary waves, such that the more pointed segments of the crestline face downcurrent" (Allen, 1968, p.62-63). It differs from a lunate ripple in having lesser curvature of the crestline. Catenary ripples may be in or out of phase with the ripples immediately upstream or downstream.
