Automatically move to the next video in the Classroom when playback concludes
- 1 Intro
- 2 The last 34 Myr documents the evolution from a unipolar to bipolar world
- 3 Carbonate deposition is an important part of the carbon cycle
- 4 Carbonate deposition in the Atlantic Ocean was poorly understood
- 5 X-Ray Fluorescence Core Scanning unlocks the sediments chemical composition
- 6 We XRF core scanned the entirety of Site 1264 between 2011 and 2018
- 7 The XRF data could help ensure stratigraphic continuity
- 8 CODD: generate composite core photos...
- 9 CODD: ... and composite splice core photos
- 10 We used different tuning approaches from 8-0 Ma because eccentricity was weaker
- 11 The orbital imprint on Caco, deposition shows three distinct phases
- 12 Eccentricity-paced cyclicity (dissolution?) dominates during Miocene warmth
- 13 The MCO may have been preconditioned by early Miocene warmth
- 14 Precession-driven deposition prevails after the mid Miocene climate transition
- 15 High-latitude biomes drove this
- 16 The stronger high-latitude processes coincide with the -8 Ma onset of the LMBB
- 17 The LMBB is globally recognised, but the origins are not yet understood
- 18 The LMBB onset seems synchronous between the Atlantic and the Pacific
- 19 Increased nutrients may come from...
- 20 The global nutrient distribution may reflect regional differences in...
- 21 New insights into the LMBB indicate...

- 23 Current version CODD 2.1 for IGOR Pro 7 & 8
- 24 A 30 million year CaCO, view of climate, cry and carbon cycle interactions
