Microstructure and composition of marine aggregates as co-determinants for vertical particulate organic carbon transfer in the global ocean
Publication Type: Academic Journal
Source(s): Biogeosciences, Vol 17, Pp 1765-1803 (2020)
Abstract: Marine aggregates are the vector for biogenically bound carbon and nutrients from the euphotic zone to the interior of the oceans. To improve the representation of this biological carbon pump in the global biogeochemical HAMburg Ocean Carbon Cycle (HAM...
Spatial and Temporal Patterns of Pore Water Chemistry in the Inter-Tidal Zone of a High Energy Beach
Publication Type: Academic Journal
Source(s): Frontiers in Marine Science, Vol 6 (2019)
Abstract: Submarine groundwater discharge (SGD) is a ubiquitous source of meteoric fresh groundwater and recirculating seawater to the coastal ocean. Due to the hidden distribution of SGD, as well as the hydraulic- and stratigraphy-driven spatial and temporal he...
Settling of highly porous and impermeable particles in linear stratification: implications for marine aggregates.

Terrestrial-type nitrogen-fixing symbiosis between seagrass and a marine bacterium
Publication Type: Periodical
Source(s): Nature; December 2021, Vol. 600 Issue: 7887 p105-109, 5p
Abstract: Symbiotic N2-fixing microorganisms have a crucial role in the assimilation of nitrogen by eukaryotes in nitrogen-limited environments1–3. Particularly among land plants, N2-fixing symbionts occur in a variety of distantly related plant lineages and oft...
Anaerobic endosymbiont generates energy for ciliate host by denitrification
Publication Type: Periodical
Source(s): Nature; March 2021, Vol. 591 Issue: 7850 p445-450, 6p
Abstract: Mitochondria are specialized eukaryotic organelles that have a dedicated function in oxygen respiration and energy production. They evolved about 2 billion years ago from a free-living bacterial ancestor (probably an alphaproteobacterium), in a process...
Permeability shapes bacterial communities in sublittoral surface sediments.

Simultaneous visualization of flow fields and oxygen concentrations to unravel transport and metabolic processes in biological systems
Publication Type: Periodical
Source(s): Cell Reports Methods; May 2022, Vol. 2 Issue: 5
Abstract: From individual cells to whole organisms, O2transport unfolds across micrometer- to millimeter-length scales and can change within milliseconds in response to fluid flows and organismal behavior. The spatiotemporal complexity of these processes makes t...
Diverse methylotrophic methanogenic archaea cause high methane emissions from seagrass meadows.

Ciliary flows in corals ventilate target areas of high photosynthetic oxygen production.
Publication Type: Academic Journal
Source(s): Current biology : CB [Curr Biol] 2022 Oct 10; Vol. 32 (19), pp. 4150-4158.e3. Date of Electronic Publication: 2022 Aug 23.
Abstract: Most tropical corals live in symbiosis with Symbiodiniaceae algae whose photosynthetic production of oxygen (O 2 ) may lead to excess O 2 in the diffusive boundary layer (DBL) above the coral surface. When flow is low, cilia-induced mixing of the coral...
