摘要

描述

English: Chart showing heat content of ocean, top 2000m and top 700m, since 1957

Source for Version 7: Top 700 meters: Lindsey, Rebecca; Dahlman, Luann. Climate Change: Ocean Heat Content. climate.gov. National Oceanic and Atmospheric Administration (NOAA) (6 September 2023). Archived from the original on 29 October 2023. ● Top 2000 meters: Ocean Warming / Latest Measurement: December 2022 / 345 (± 2) zettajoules since 1955. NASA.gov. National Aeronautics and Space Administration. Archived from the original on 20 October 2023.
Five-year averaging is native to the NASA source for 2000m. Uploader performed 5-year averaging of the NOAA source's annual values, so that traces would be consistent.
Technical note: most SVG code for Version 7 was automatically generated by the "Line charts" spreadsheet linked at User:RCraig09/Excel to XML for SVG. Additions and adjustments were made in a text editor.

Source for Version 1, which includes raw data from which the above SVG chart was generated: Lindsey, Rebecca; Dahlman, Luann, Climate Change: Ocean Heat Content. climate.gov. National Oceanographic and Atmospheric Administration (NOAA) (17 August 2020). Archived from the original on 25 February 2023. Embedded data link leads to data that is more current than 2020 publication date of article.

Most of the SVG code for Version 1 was automatically generated by the "Vertical bar charts" spreadsheet linked at User:RCraig09/Excel to XML for SVG. Bars' colors were manually added, though possibly the "Warming stripes bar chart" spreadsheet could have achieved the same result more directly.

当前	2024年2月4日 (日) 23:28	1,200 × 675（4 KB）	RCraig09	Version 8: switch shades of red, since it's the shallower depths that have the absorbed the most heat from the atmosphere
	2024年1月21日 (日) 22:55	1,200 × 675（5 KB）	RCraig09	Version 7: switch to red color scheme, to reflect that red=hot (and blue=cool)
	2023年10月29日 (日) 18:54	1,200 × 675（5 KB）	RCraig09	VERSION 6: Added "Top 2000m" trace . . . changing to line chart . . . changing to centered 5-year average that is native to NASA source
	2023年10月18日 (三) 19:27	1,200 × 675（12 KB）	RCraig09	Version 5: broke down vertical axis label into three separate text elements, to work around ongoing SVG text rendering bug on Wikimedia
