Stratigraphic unit

A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.

Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".

Lithostratigraphic units

Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.

Bed

A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.

Member

A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.

1994 Group

The 1994 Group was a coalition of smaller research-intensive universities in the United Kingdom, founded in 1994 to defend these universities' interests following the creation of the Russell Group by larger research-intensive universities earlier that year. The 1994 Group originally represented seventeen universities, rising to nineteen, and then dropping to eleven. The Group started to falter in 2012, when a number of high performing members left to join the Russell Group. The 1994 Group ultimately dissolved in November 2013.

Role

The group sought "to represent the views of its members on the current state and the future of higher education through discussions with the government, funding bodies, and other higher education interest groups" and "[made] its views known through its research publications and in the media".

University Alliance, million+, GuildHE and the Russell Group were its fellow university membership groups across the UK higher education sector.

TSX-5

TSX-5 (Tri-Service-Experiments mission 5), is a $85 million satellite successfully launched into orbit on June 7, 2000 from Vandenberg Air Force Base on a Pegasus XL rocket.

TSX-5 hosts two Department of Defense (DOD) payloads, STRV-2 (the Space Test Research Vehicle-2), sponsored by the Ballistic Missile Defense Organization, and CEASE (the Compact Environmental Anomaly Sensor), sponsored by the Air Force's Phillips Geophysics Laboratory. TSX-5 is managed by the Space Technology Program (STP) at the Space and Missiles Centre, Test and Evaluation (SMC/TELS) at Kirtland Air Force Base, New Mexico.
