GRIP Ammonium Concentrations
Continuous melting technique, combined with continuous flow analysis (Sigg et al., 1994). A subcore with a cross section area of 18x18mm2 cut is used. -
Stable Isotope Data from Basal Ice, GRIP Core
Data are continuous averages for the average (midpoint) depths given. -
GRIP Carbon Dioxide measured by infrared laser absorption spectrometer, IRLS
Measurements were performed on 0.55 m long sections. For each section, several samples of size 2.5 cm (5 g) along these sections were measured and averaged. -

GRIP Dielectric Profiling (DEP) and Electrical Conductivity (ECM) averaged data
Each data point is an average over a 55 cm interval; data are correted, level changes between 730 and 930 m are believed to be spurious (Wolff, et al., 1995) due to poor... -
GRIP Oxygen Isotopes
55cm average delta 18-O values; data were used in the construction of the glaciological timescale -
GRIP Methane Data (LGGE)
Age is mean age of trapped air in kilocalendar years before 1950. Sample depth relative to surface of summer 1989. One sample =4cm core. -
GRIP Methane Data (Bern)
Depth below the surface of summer 1989. One sample = 2 cm. Age is Gas age. Data measured in Bern. -
GRIP total air content
Depth is midpoint relative to summer 1989 surface. Age is given as gas age in kilocalendar years before 1950. -
GRIP Accumulation Rates
Depth at the top of the sample -
GRIP Acidity
Data calculated from electrical conductivity; depth is given at the local maximum in the ECM record; age is given at the local acid peak -
Carbonate content of sediment core CRP-1 (Table 1)
Determinations of total carbonate content yield additional information, in the context of integrated investigations, thus enabling or enhancing the interpretation and... -
Petrographical classification and mineral assemblage of basement clasts from ...
Petrographical and mineral chemistry data are described for the mist representative basement lithologies occurring as clasts (pebble grain-size class) from the CRP-1 drillhole.... -
(Table 1) Detrital modes for sand grains in sediment core CRP-1
Detrital modes for the sand-size fraction in 24 samples from the CRP-1 drillcore are described. Most samples are largely composed of quartzo-feldspathic detritus sourced... -
Rare earth element content of the clay fraction from sediment core CRP-1 (Tab...
TEM observations on smectites and REE analyses on the clay minerals of the sediments of CRP-1 core were carried out to investigate their origin and the source rocks from which... -
Abundance of terrestrial palynomorphs of sediment core CRP-1
Sparse pollen and spores from the lower Miocene section of CRP-1 derive from at least three sources. A low-diversity but persitent angiosperm-moss-liverwort assemblage may... -
Summary of 40Ar/39Ar results from core sediment CRP-1 (Table 1)
40Ar/39Ar dating of volcanic clasts and pumice provide constraints for depositional ages of the CRP-1 core. Laser-fusion analyses of anorthoclase phenocrysts from pumice clasts...
