#Kspectra toolkit upgrade
Sold through Apple Store: $20/quarter (Pro, $130/year) upgrade discounts ImageTank and DataGraph are related (and are signed). Can use ESRI shapfiles.” It is scriptable. Program is extremely flexible and can be used for graphics, statistics, visualizations, etc Can produce animations of contours (lines and shading) generated from variably spaced data. DataTank uses the strength of Quartz to generate publication quality vector-graphics as PDF/EPS or anti-aliased bitmaps for use in web pages and presentations.ĭataTank enables interactive exploration of large data sets.ĭataTank will perform incremental evaluation, treating data sets with millions of data points and hundreds of thousands of entries the same way as a simple data set that is typed in manually.ĭennis Kahlbaum wrote: “Excellent support. Like other scientific visualization programs DataTank uses OpenGL to draw 3D graphics, and supports transparency, interactive rotation, multiple light sources and camera positions. From their web site:ĭataTank is designed for scientific visualization, data mining, and algorithm development, but it is flexible enough to be used for a variety of other uses as well. Winner of the 2005 Apple Design Award for Best Scientific Computing Solution.

Comparison of the 1262 record with a lower resolution, but orbitally-tuned benthic record for Site 1209 in the Pacific allows for verification of key features of the benthic isotope records which are global in scale including a key warming step at 57.7 Ma.Commercial statistics software for Macintosh computers (Macs) The higher amplitude 405-kyr cycles in the latest Paleocene are associated with changes in bottom water temperature of 2–4 ☌, while the most prominent 100 kyr-paced cycles can be accompanied by changes of up to 1.5 ☌.

However, these phase lags are not constant, with the lag in the 405-kyr band extending from ∼4 (±5) kyr to ∼21 (☒) kyr from the late Paleocene to the early Eocene, suggesting a progressively weaker coupling of climate and the carbon-cycle with time. These negative CIEs and δ 18O events coincide with maxima in eccentricity, with changes in δ 18O leading changes in δ 13C by ∼6 (±5) kyr in the 405-kyr band and by ∼3 (☑) kyr in the higher frequency 100-kyr band on average. During the course of the Early Paleogene record, and particularly in the latest Paleocene, eccentricity-paced negative carbon-isotope excursions ( δ 13C, CIEs) and coeval negative oxygen-isotope ( δ 18O) excursions correspond to low carbonate (CaCO 3) and coarse fraction (%CF) values due to increased carbonate dissolution, suggesting shoaling of the lysocline and accompanied changes in the global exogenic carbon cycle. Obliquity (41 kyr) is almost absent throughout the section except for a few brief intervals where it has a relatively weak influence. The main pacemaker in the benthic oxygen-isotope ( δ 18O) and carbon-isotope ( δ 13C) records from ODP Site 1262, are the long (405 kyr) and short (100 kyr) eccentricity cycles, and precession (21 kyr). This high resolution (∼2–4 kyr) record allows the changing character and phasing of orbitally-modulated cycles to be studied in unprecedented detail as it reflects the long-term trend in carbon cycle and climate over this interval. Here we present a 7.7 million year (myr) long, high-resolution, orbitally-tuned, benthic foraminiferal stable-isotope record spanning the late Paleocene and early Eocene interval (∼52.5–60.5 Ma) from Ocean Drilling Program (ODP) Site 1262, South Atlantic. While these hyperthermals, such as the Paleocene Eocene Thermal Maximum (PETM), have been studied in great detail, the background low-amplitude cycles seen in carbon and oxygen-isotope records throughout the Paleocene–Eocene have hitherto not been resolved.

The Late Paleocene and Early Eocene were characterized by warm greenhouse climates, punctuated by a series of rapid warming and ocean acidification events known as “hyperthermals”, thought to have been paced or triggered by orbital cycles.
