Maps of tidal energy dissipation rates, that were calculated for three different rotation periods (12h, 18h and 24h) using the Oregon State Tidal Inversion Software, are implemented as oceanic bottom heat flux into CLIMBER-3α to investigate the impact of tides on early Earth’s climate.
For each length of day corresponding paleoclimatic scenarios each of which with three different atmospheric carbon dioxide abundances, are simulated.
We use the relatively fast intermediate-complexity model CLIMBER-3α to be able to run a large number of simulations. CLIMBER-3α consists of (1) an improved version of the ocean general circulation model MOM3 run at a coarse horizontal resolution of 3.75 x 3.75 degrees with 24 vertical layers, (2) the sea-ice model ISIS operated at the same horizontal resolution and capturing both the thermodynamics and dynamics of sea ice, and (3) the fast statistical--dynamical atmosphere model POTSDAM-2 with grid cells measuring 22.5 degrees in longitude and 7.5 degrees in latitude.
The main limitations of the model relate to its simplified atmosphere component.
Tide model simulations of the Oregon State Tidal Inversion Software were used to compute tidal energy dissipation data. For more details see the corresponding article (Biewald et al., XXXX)
sandbox is an R-tool for probabilistic numerical modelling of sediment properties. A flexible framework for definition and application of time/depth- based rules for sets of parameters for single grains that can be used to create artificial sediment profiles. Such profiles can be used for virtual sample preparation and synthetic, for instance, luminescence measurements.
The Lake Junín Drilling Project, co-funded by the International Continental Scientific Drilling Program, ICDP, aims to provide a continuous paleoclimate record from lacustrine sediments, and to reconstruct the history of the continental records covering the glacial-interglacial cycles spanning more than 500 kyr. Lake Junín, also known as Chinchaycocha, is a shallow (maximum water depth of 12 m), inter-mountain high-elevation (at 4100 m a.s.l.) lake in the inner-tropics of the Southern Hemisphere that spans 300 km2 in the tropical Andes of Peru. Drill cores were recovered during summer 2015 from three drill sites on the lake. After the completion of coring operations in each hole, downhole logging measurements were performed in five of the 11 boreholes (1A, 1C, 1D, 2A and 3B) by the Operational Support Group of ICDP at GFZ Potsdam (OSG).
The OSG logging data from Lake Junín Drilling Project is given here in three data formats. For each of the five boreholes all processed logging data are comprised in one composite logging data set, this set is given here both in ASCII text and in WellCAD format. Additionally, the raw sonic waveform data are in LIS format:
• Composite logging data in ASCII text files (.txt)
• Composite logging data in WellCAD format (.wcl)
• Sonic raw data (waveforms) in LIS format (.lis)
