“…The DFA's results of the Arctic HAUSGARTEN time-series (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) revealed strong relationships between the phytoplankton composition and concentrations of biogenic sediment compounds, indicating organic matter in surface sediments with the explanatory variables chosen for our analysis. Higher amounts of sedimentbound chloroplastic pigments seemed to provide additional food supply for meiofauna and megafauna, which resulted in increases in abundance with a time lag of 1-2 years in larger organism size classes, as also found in other deep-sea areas (Sibuet et al 1989;Rowe and Pariente 1992;Kröncke et al 2013b).…”

“…Quantitative and qualitative changes in phytoplankton have unavoidable consequences at the other trophic levels. Several studies of benthic communities revealed that their diversity and function depended on the amount and quality of organic matter produced in the water column, even at extreme depths (Rowe and Pariente 1992;Clare et al 2017). The DFA's results of the Arctic HAUSGARTEN time-series (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) revealed strong relationships between the phytoplankton composition and concentrations of biogenic sediment compounds, indicating organic matter in surface sediments with the explanatory variables chosen for our analysis.…”

Data from five sites of the International Long Term Ecological Research (ILTER) network in the North-Eastern Pacific, Western Arctic Ocean, Northern Baltic Sea, South-Eastern North Sea and in the Western Mediterranean Sea were analyzed by dynamic factor analysis (DFA) to trace common multi-year trends in abundance and composition of phytoplankton, benthic fauna and temperate reef fish. Multiannual trends were related to climate and environmental variables to study interactions. Two common trends in biological responses were detected, with temperature and climate indices as explanatory variables in four of the five LTER sites considered. Only one trend was observed at the fifth site, the Northern Baltic Sea, where no explanatory variables were identified. Our findings revealed quasi-synchronous biological shifts in the different marine ecosystems coincident with the 2000 climatic regime shift and provided evidence on a possible further biological shift around 2010. The observed biological modifications were coupled with abrupt or continuous increase in sea water and air temperature confirming the key-role of temperature in structuring marine communities.

Deep‐Ocean Ecosystems

The term ‘deep ocean’ typically describes any marine ecosystem located at depths higher than 500 m. This environment is characterised by an elevated hydrostatic pressure, an average temperature of 2–4 °C, the absence of sunlight and the scarce availability of organic food. Specific organisms are associated with the deepest areas, and pressure‐adapted animals as well as microorganisms inhabit these peculiar ecosystems. It is difficult to understand how we do not know much about deep sea compared to space environment, despite the fact that its distance from the ocean surface is relatively short. With no doubt, the deep‐sea biodiversity is still mostly unseen and important benefits to human health and industrial activities will be available in the future from more extensive studies on this fascinating environment. Key Concepts: The deep sea is the world's largest ecosystem. The deep‐sea biodiversity is still mostly unseen. The less diversity of animals with increasing depths is mainly due to the hydrostatic pressure, as well as to a larger competition for food coupled with a lower basal metabolism. Further insights into the natural traits of deep‐sea will lead to important benefits to human health and industrial applications. Despite the fact that the distance of deep‐sea from the ocean surface is much shorter than that between Earth and space, the abyssal environment is far to be well known.
