Detecting Marine Heatwaves With Sub-Optimal Data

Marine heatwaves (MHWs), or prolonged periods of anomalously warm sea water temperature, have been increasing in duration and intensity globally for decades. However, there are many coastal, oceanic, polar, and sub-surface regions where our ability …


An R package for the detection of heatwaves and cold-spells.


An R package with useful functions for coastal oceanography.

Detecting marine heatwaves with sub-optimal data

Research conducted on how sub-optimal a time series may be and still produce comparable marine heatwaves to an optimal time series.

heatwaveR: A central algorithm for the detection of heatwaves and cold-spells

Predominant Atmospheric and Oceanic Patterns during Coastal Marine Heatwaves

As the mean temperatures of the worlds oceans increase, it is predicted that marine heatwaves (MHWs) will occur more frequently and with increased severity. However, it has been shown that variables other than increases in sea water temperature have …

Nearshore and offshore co-occurrence of marine heatwaves and cold-spells

A changing global climate places shallow water ecosystems at more risk than those in the open ocean as their temperatures may change more rapidly and dramatically. To this end, it is necessary to identify the occurrence of extreme ocean temperature …

Climate Change in Coastal Waters: Time Series Properties Affecting Trend Estimation

In South Africa, 129 in situ temperature time series of up to 43 years are used for investigations of the thermal characteristics of coastal seawater. They are collected with handheld thermometers or underwater temperature recorders (UTRs) and are …
