Abstract Indo‐Pacific humpback dolphins ( Sousa chinensis ) inhabit shallow coastal waters of the region including southeast China, with at least 6 putative populations identified to date in Chinese waters. However, connectivity among these has not yet been fully investigated. In present study, we compared and cross‐matched photographic catalogs individual collected Pearl River Delta region, Leizhou Bay, Sanniang southwest Hainan Island, a total 3158 individuals, found no re‐sighting 4 study...
Abstract. The Peruvian upwelling system hosts a marine ecosystem with extremely high productivity. Observations show that the is only eastern boundary (EBUS) an out-of-phase relationship between seasonal surface chlorophyll concentrations and intensity. This “seasonal paradox” triggers following questions: (1) what are unique characteristics of system, compared other EBUSs, lead to relationship, (2) how does paradox influence functioning? Using observational climatologies for four we...
The meridional overturning circulation in the North Atlantic supplies oxygen to a large part of world ocean's interior via formation mode waters and Deep. Whether human activities have altered this ventilation system remains uncertain. To assess temporal changes ocean Atlantic, we calculated "age" seawaters, that is duration since its last contact with surface, from both observed climate models simulated chlorofluorocarbon-12 sulfur hexafluoride concentrations. Results suggest enhanced...
Coastal upwelling, driven by alongshore wind that pushes surface waters away from the shore, brings nutrient-rich, cold, deep to surface, fueling productivity and biodiversity in marine ecosystems. The Northern Humboldt Current System, as one of most productive coastal upwelling systems, is renowned for its high fish catches due persistent upwelling. Since cannot be directly measured, scientists rely on indices estimate it through upward velocity, Ekman transport, temperature gradients....
Understanding the drivers and potential impacts of environmental variability on distribution Peruvian anchovies, largest single-species fishery planet, is essential for their proper management in a changing world. However, intricate interactions these organisms require use complex models such as machine learning methods. In this study, we compared three methods producing habitat maps anchovies: traditional Generalised Additive Models, XGBoost which form supervised new method based clustering...
Abstract. Phytoplankton form the base of marine food web by transforming CO2 into organic carbon via photosynthesis. Despite importance phytoplankton for ecosystems and global cycling, projections biomass in response to climate change differ strongly across Earth system models, illustrating uncertainty our understanding underlying processes. Differences are especially large Southern Ocean, a region that is notoriously difficult represent models. Here, we argue total (depth-integrated) Ocean...
Abstract The Humboldt Upwelling System is of global interest due to its importance fisheries, though the origin high productivity remains elusive. In regional physical‐biogeochemical model simulations, seasonal amplitude mesozooplankton net production exceeds that phytoplankton, indicating “seasonal trophic amplification.” An analytical approach identifies amplification be driven by a seasonally varying transfer efficiency mixed layer variations. latter alters vertical distribution...
The Northern Humboldt Current System is the most productive eastern boundary upwelling system, generating about 10 % of global fish production, mainly coming from small pelagic fish. It bottom-up and top-down affected by environmental anthropogenic variability, such as El-Niño Southern Oscillation fishing pressure, respectively. high variability in this well their economic importance, call for a careful management aided use end-to-end models. This type models represent ecosystem whole,...

Abstract The Humboldt Upwelling System hosts a highly productive ecosystem with central importance for global fisheries, yet strong seasonal and interannual variability in the planktonic base of food chain ultimately affecting fish yield. Understanding energy transfer within plankton community contemporary climate can provide valuable insights future projections dynamics. Therefore, we use regional physical-biogeochemical ocean model simulation (CROCO-BioEBUS) from 1990 to 2010 investigate...

Abstract. The Peruvian Upwelling System hosts an extremely high productive marine ecosystem. Observations show that the is only Eastern Boundary Systems (EBUS) with out-of-phase relationship of seasonal surface chlorophyll concentrations and upwelling intensity. This "seasonal paradox" triggers questions: (1) what uniqueness compared other EBUS leads to out phase relationship; (2) how does this lead low phytoplankton biomass in austral winter despite strong ample nutrients? Using...
Abstract. Phytoplankton forms the base of marine food web by transforming CO2 into organic carbon via photosynthesis. Some is then transferred through and exported deep ocean, a process known as biological pump. Despite importance phytoplankton for ecosystems global cycle, projections biomass in response to climate change differ strongly across Earth system models, illustrating uncertainty our understanding underlying processes. Differences are especially large Southern Ocean, region that...
Phytoplankton, as the base of marine food web, has great importance for ecosystems and global carbon cycle. However, Earth system models indicate considerable uncertainty our knowledge about underlying processes that determine phytoplankton evolution under climate change. Particularly large differences between can be found in Southern Ocean, a region notorious its difficulty modeling. The objective this study is to analyze potential response change from both "bottom-up" "top-down"...
