In this paper, we specifically address how strong the climate change signal will be in ocean colour and the different factors that affect it. We determine which optical property is likely to respond most rapidly to climate change, and thus should be the focus of efforts to detect robust climate-driven trends in satellite ocean colour records. The model also allows for estimating Chl-a from the model RRS in a similar way to the typical real world ocean colour Chl-a product 2.
As such, we use the model to consider the implications of using satellite-derived Chl-a for monitoring climate trends. Results The present day and interannual variability The current day biogeochemical and ecosystem model fields have been validated against and compare well to observations see Methods, Supplementary Figs.
Chl-a Fig. These regions are dominated by larger phytoplankton cells Supplementary Fig. Chl-a is much lower in the subtropical gyres; here nutrient supplies are low and pico-phytoplankton, with their high nutrient affinity, dominate. Interannual variability defined as the standard deviation of the annual mean composites — : d model actual; e model satellite-like derived; f OC-CCI, v2 satellite derived.
White areas are regions where model resolution is too coarse to capture the smaller seas, or where there is persistent ice cover. Model actual Chl-a is the sum of the dynamic Chl-a for each phytoplankton type that is explicitly resolved in the model.
It is equivalent to the Chl-a that would be measured in situ. This is distinct to satellite-derived Chl-a which is calculated via an algorithm derived from the reflected light measured by ocean colour satellite instruments Full size image A unique feature of this model is the explicit parameterization of upwelling and downwelling irradiance, such that we can calculate RRS see Methods.
In the model, RRS is resolved over the visible spectrum from to nm in 25 nm bands. We note that the model RRS does not have the uncertainties that the real world RRS has due to the atmospheric correction 1. The model does not have the exact same wavebands as the ocean colour satellites, therefore we interpolate the model RRS to the same bands as the satellite measurements Fig. The model captures the reversed patterns between blue nm and green nm RRS between gyres and highly productive regions.
The model underestimates the blue RRS in the subtropics where modelled Chl-a is likely too low relative to the real ocean Fig.
The model has noticeably higher green nm RRS in the equatorial Atlantic and Indian Ocean than the satellite measurements, but this is consistent with the model over-estimating Chl-a relative to the satellite product in this region Fig. These are also regions of high cloud cover where the satellite product may be biased.
White areas are regions where model resolution is too coarse to capture the smaller seas or regions of constant ice cover. Statistics of comparison of model and all six observed wavebands are provided in Supplementary Figs. This proxy for Chl-a is derived from the model reflectance fields and will be called derived Chl-a. This is a different property to model actual Chl-a which is the sum of the dynamic Chl-a that is explicitly resolved and is thus more equivalent to the Chl-a that would be measured in situ.
This product Fig. Ocean ecosystems, and therefore ocean colour, are not static, changing with the seasons and interannually Fig.
The model Fig. The model Equatorial Pacific has a narrower band of variability around the equator than seen in the observations Supplementary Fig. The RRS variability is otherwise generally underestimated.
We find it instructive to also examine the magnitude of the interannual variability relative to the climatological mean composite Fig. The current day relative magnitude of interannual variability of the other optically important constituents CDOM, detrital particles are predicted by the model to have similar values to Chl-a.
However, the relative magnitude of the observed interannual variability of RRS is lower red symbols in Fig. The model captures these lower ratios though underestimates the variability, as in Chl-a over most of the spectrum, but not at the high wavelength bands Fig. However, we note that the uncertainty in RRS is higher at higher wavelength bands Global median of the ratio of the annual composite temporal standard deviation to the 18 year mean composite for a satellite derived Chl-a dChl , actual Chl-a Chl , detrital matter det and CDOM; and for b remotely sensed reflectance.
See Supplementary Fig. The meridional overturning circulation slows and shallows relative to current day conditions. These changes lead to a reduction in the supply of macronutrients from depth.

The shades displayed on your device are indicative and are not exact representations of the actual paint colours. Kindly verify the shade with the Colour Spectra or shade card before painting. On-screen colour representation depends on the colour system being used by the computer or tablet or mobile screen. The shades displayed on this site are indicative and are not precise representations of actual paint colours due to variance in monitor calibrations and resolution as well as screen settings.
While scientific tools have been used to match colours and make them look like the paint you will use, yet, there is likely to be a difference. We offer ml samplers of our products at select Colour World outlets, which can be tinted to any colour of your choice.
