“…The fisheries catches data were sourced from the Sea Around Us (www.seaaroundus.org), which originated from a range of sources including the Food and Agriculture Organization's (FAO) fisheries database, supplemented by national data sets from the countries adjacent to these three LMEs, from North Korea in the north to Indonesia in the south (Zeller et al, 2016; see also contributions in Pauly and Zeller, 2016b). These catches data were "reconstructed" in the sense that where they were missing, FIGURE 1 | The three Large Marine Ecosystems adjacent to the Chinese coast, i.e., the Yellow Sea, the East China Sea, and the South China Sea.…”

Impacts of Ocean Warming on China's Fisheries Catches: An Application of “Mean Temperature of the Catch” Concept

2018

Ocean warming can strongly impact marine fisheries; notably, it can cause the "mean temperature of the catch" (MTC) to increase, an indicator of the tropicalization of fisheries catches. In this contribution, we explore MTC changes in three large marine ecosystems (LMEs) along China's coasts, i.e., the Yellow Sea, East China Sea, and South China Sea LMEs, and their relationships to shifts of sea surface temperature (SST). The results show that, while the MTCs began to increase in 1962 in the East China Sea and in 1968 in the Yellow Sea, there was no detectable increase in the South China Sea. There also was a strong relationship between MTC and SST in the Yellow and East China Seas from 1950 to 2010, especially when taking a 3-year time-lag into account. The lack of change of the MTC in the South China Sea is attributed to the relatively small increase in SST over the time period considered, and the fact that the MTC of tropical ecosystems such as the South China Sea is not predicted to increase in the first place, given that their fauna cannot be replaced by another, adapted to higher temperature. Overall, these results suggest that ocean warming is already having an impact on China's marine fisheries, and that policies to curtail greenhouse gas emissions are urgently needed to minimize the increase of these impacts on fisheries.

“…Circulation-induced changes dominate the change of −12 % in RCP4.5 too. This region is today a very productive fishery area (Zeller et al, 2016), so a significant decrease in NPP could have adverse effects on fish catches. It is therefore noteworthy that all RM methods yield NPP changes only marginally smaller than those in RCP8.5 and not nearly as small as those in RCP4.5.…”

Climate engineering and the ocean: effects on biogeochemistry and primary production

Abstract. Here we use an Earth system model with interactive biogeochemistry to project future ocean biogeochemistry impacts from the large-scale deployment of three different radiation management (RM) climate engineering (also known as geoengineering) methods: stratospheric aerosol injection (SAI), marine sky brightening (MSB), and cirrus cloud thinning (CCT). We apply RM such that the change in radiative forcing in the RCP8.5 emission scenario is reduced to the change in radiative forcing in the RCP4.5 scenario. The resulting global mean sea surface temperatures in the RM experiments are comparable to those in RCP4.5, but there are regional differences. The forcing from MSB, for example, is applied over the oceans, so the cooling of the ocean is in some regions stronger for this method of RM than for the others. Changes in ocean net primary production (NPP) are much more variable, but SAI and MSB give a global decrease comparable to RCP4.5 ( ∼ 6 % in 2100 relative to , while CCT gives a much smaller global decrease of ∼ 3 %. Depending on the RM methods, the spatially inhomogeneous changes in ocean NPP are related to the simulated spatial change in the NPP drivers (incoming radiation, temperature, availability of nutrients, and phytoplankton biomass) but mostly dominated by the circulation changes. In general, the SAI-and MSB-induced changes are largest in the low latitudes, while the CCT-induced changes tend to be the weakest of the three. The results of this work underscore the complexity of climate impacts on NPP and highlight the fact that changes are driven by an integrated effect of multiple environmental drivers, which all change in different ways. These results stress the uncertain changes to ocean productivity in the future and advocate caution at any deliberate attempt at large-scale perturbation of the Earth system.

“…Total marine fisheries catches from 1950 to 2014 were estimated using the well-established catch reconstruction approach of Zeller et al (2016), which was initially applied in Zeller et al (2006) and first described in Zeller et al (2007). The present contribution is an update of the original catch reconstruction of Thailand's marine fisheries from 1950-2010 which is detailed in Teh et al (2015) 2 .…”
