Atlantic Meridional Transect (AMT)
Years of record
- to
"The Atlantic Meridional Transect (AMT) is a multidisciplinary programme which undertakes biological, chemical and physical oceanographic research during an annual voyage between the UK and destinations in the South Atlantic." As of early November, 2013, there have been 23 cruises. AMT data have resulted in many publications including three special issues.

Atlantic Multi-decadal Oscillation (AMO) and Atlantic Multidecadal Variability (AMV)
Years of record
- to
The Atlantic Multi-decadal Oscillation (AMO) has been identified as a coherent mode of natural variability occurring in the North Atlantic Ocean with an estimated period of 60-80 years. It is based upon the average anomalies of sea surface temperatures (SST) in the North Atlantic basin, typically over 0-80N. To remove the climate change signal from the AMO index,…

CARINA: Carbon in the North Altantic
Years of record
- to
The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and US partners. It has produced a merged internally consistent data set of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the…

Coral geochemical records: An overview of their use as climate proxies and of available databases
Years of record
- N/A
Coral records are one of the main types of high-resolution (annual to sub-annual) paleoclimate proxies, providing timeseries of environmental conditions reaching hundreds to thousands of years into the past in the tropics, the central driver of the global atmospheric circulation. As such, corals complement paleoclimate records from the largely mid-latitude tree-…

Hurrell North Atlantic Oscillation (NAO) Index (PC-based)
Years of record
- to
The principal component (PC)-based indices of the North Atlantic Oscillation (NAO) are the time series of the leading Empirical Orthogonal Function (EOF) of SLP anomalies over the Atlantic sector, 20°-80°N, 90°W-40°E. These indices are used to measure the NAO throughout the year, tracking the seasonal movements of the Icelandic low and Azores high. These movements…

Hurrell North Atlantic Oscillation (NAO) Index (station-based)
Years of record
- to
The winter (December thru March) station-based index of the NAO is based on the difference of normalized sea level pressure (SLP) between Lisbon, Portugal and Stykkisholmur/Reykjavik, Iceland since 1864. Positive values of the NAO index are typically associated with stronger-than-average westerlies over the middle latitudes, more intense weather systems over…

Hurrell wintertime SLP-based Northern Annular Mode (NAM) Index
Years of record
- to
The NAM (or Arctic Oscillation) is defined as the first EOF of NH (20°-90°N) winter SLP data. It explains 23% of the extended winter mean (December-March) variance, and it is clearly dominated by the NAO structure in the Atlantic sector. Although there are some subtle differences from the NAO regional pattern over the Atlantic and Arctic (see Figure 1 below), the main…

Meridional Modes and their indices
Years of record
- N/A
In each of the world’s tropical ocean basins, year-to-year climate variability is primarily governed by fluctuations in the zonal sea surface temperature (SST) gradient and zonal surface winds. These variations consist of recognizable climate modes, such as the El Niño-Southern Oscillation (ENSO) in the tropical Pacific and Atlantic Niño in the tropical Atlantic. While…

RAPID: monitoring the Atlantic Meridional Overturning Circulation at 26.5°N
Years of record

"The Rapid Climate Change programme (RAPID) explores what causes rapid switches in climate, with a main (but not exclusive) focus on the Atlantic Ocean's thermohaline circulation." "A principal objective of the RAPID programme is the development and maintenance of a pre-operational prototype system that will continuously observe the strength and structure of the MOC. An…
