Exchange Dynamics Reveal Significant Accumulation of Dimethylated Sulfur by Mediterranean Benthic Communities

Frontiers in Marine Science, 2017
One fifth of Mediterranean waters can be classified as shelf—much higher than the global average. Consequently, the shelf/coastal zone plays a proportionally greater biogeochemical role than in the major oceans, including the support of a wide range of ...

Food web modifications shifted the functional structure of zooplankton

Limnology and Oceanography, EarlyView.
Abstract The North Sea has been undergoing long‐term transformations driven by shifts in human activities and climate change, which have jointly reshaped the composition of marine communities. Despite existing studies, the functional mechanisms driving community changes remain poorly understood.

Ballasted Flocs Capture Pelagic Primary Production and Alter the Local Sediment Characteristics in the Coastal German Bight (North Sea)

Geosciences, 2019
Suspended, organic matter, especially in the form of adhesive extracellular polymers (EPS), tends to form flocs, which may also incorporate suspended lithogenic particles in coastal environments. With an increased settling velocity, these ballasted flocs

Coupling air–water CO2 flux and primary production dynamics under hydrologic variability in a large urban estuary

Limnology and Oceanography Letters, EarlyView.
Abstract Estuaries are critical for land‐ocean carbon exchange, but coupling mechanisms between air–sea CO2 fluxes (FCO2) and phytoplankton gross primary productivity (GPP) remain poorly understood. This study used high‐frequency underway monitoring in the Lingdingyang Estuary to resolve spatiotemporal interplays between FCO2 and GPP.

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters

Limnology and Oceanography Letters, EarlyView.
Abstract Robust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable isotope (δ13C‐CH4) profiles along oxygen and salinity gradients.

Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity

Limnology and Oceanography Letters, EarlyView.
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales.

Continuous determination of dissolved inorganic carbon fluxes from pumping suspension feeders

Limnology and Oceanography: Methods, EarlyView.
Abstract Suspension‐feeding organisms play a pivotal role in the cycling of carbon in the oceans. They filter large amounts of water, filter out organic matter, remineralize it, and release respiratory CO2 back into the water column. Measuring emissions of respiratory CO2 in situ from suspension feeders poses the challenge of detecting small changes in

Using environmental DNA to detect Microseira wollei (Oscillatoriales), a benthic harmful algal bloom, in Lake St. Clair (Michigan, USA)

Limnology and Oceanography: Methods, EarlyView.
Abstract Microseira wollei is a benthic cyanobacterium that can cause harmful algal blooms (HABs) and often requires management. However, a pervasive challenge for M. wollei management is characterizing the spatial and temporal extent of an impacted area, which can be time and resource intensive.

Autonomous, high‐frequency and long‐term monitoring of substrate temperature in rocky intertidal zones

Limnology and Oceanography: Methods, EarlyView.
Abstract Intertidal zones are characterized by complex and dynamic thermal mosaics, where organisms experience extreme temperature variations influenced by microclimatic factors. However, accurately monitoring rocky shore temperatures over the long term remains challenging due to the limitations of conventional temperature loggers.
