Distinct gelatinous zooplankton communities across a dynamic shelf sea [PDF]

Limnology and Oceanography, 2019
AbstractUnderstanding how gelatinous zooplankton communities are structured by local hydrography and physical forcing has important implications for fisheries and higher trophic predators. Although a large body of research has described how fronts, hydrographic boundaries, and different water masses (e.g., mixed vs.

Gelatinous larvacean zooplankton can enhance trophic transfer and carbon sequestration

Trends in Ecology & Evolution, 2023
Larvaceans are gelatinous zooplankton abundant throughout the ocean. Larvaceans have been overlooked in research because they are difficult to collect and are perceived as being unimportant in biogeochemical cycles and food-webs. We synthesise evidence that their unique biology enables larvaceans to transfer more carbon to higher trophic levels and ...

Automated Gelatinous Zooplankton Acquisition and Recognition

2014 ICPR Workshop on Computer Vision for Analysis of Underwater Imagery, 2014
Much is still unknown about marine plankton abundance and dynamics in the open and interior ocean. Especially challenging is the knowledge of gelatinous zooplankton distribution, since it has a very fragile structure and cannot be directly sampled using traditional net based techniques.

Salp blooms drive strong increases in passive carbon export in the Southern Ocean

Nature Communications, 2023
Gelatinous bloom-forming zooplankton—salps—alter microbial communities and quintuple the flux of sinking particles from the surface to the deep, strongly enhancing the ability of the ocean to sequester CO2.

Collection and Culture Techniques for Gelatinous Zooplankton

The Biological Bulletin, 2003
Gelatinous zooplankton are the least understood of all planktonic animal groups. This is partly due to their fragility, which typically precludes the capture of intact specimens with nets or trawls. Specialized tools and techniques have been developed that allow researchers and aquarists to collect intact gelatinous animals at sea and to maintain many ...

Omnivory by the Small Cosmopolitan Hydromedusa Aglaura Hemistoma [PDF]

, 2005
We investigated the feeding of the small hydromedusa, Aglaura hemistoma (bell diameter \u3c 4 mm), to determine if it occupies a trophic position similar to that of large medusae.

Interactions of gelatinous zooplankton within marine food webs [PDF]

Journal of Plankton Research, 2015
Gelatinous zooplankton (GZ) comprise a taxonomically and functionally diverse group of marine organisms which includes ctenophores, cnidarians and pelagic tunicates, sharing a soft, mostly transparent body texture, a high body water content and a lack of exoskeleton.

Under-ice observations by trawls and multi-frequency acoustics in the Central Arctic Ocean reveals abundance and composition of pelagic fauna

Scientific Reports, 2023
The rapid ongoing changes in the Central Arctic Ocean call for baseline information on the pelagic fauna. However, sampling for motile organisms which easily escape vertically towed nets is challenging.

Medusae and ctenophores from the Bahia Blanca Estuary and neighboring inner shelf (Southwest Atlantic Ocean, Argentina) [PDF]

, 2017
An updated checklist of medusae and ctenophores is presented for the first time for the area comprised by the Bahía Blanca Estuary, the adjacent shelf El Rincón and Monte Hermoso beach, on the southwest coast of Buenos Aires province (Argentina).

Looking inside the Ocean: Toward an Autonomous Imaging System for Monitoring Gelatinous Zooplankton

Sensors, 2016
Marine plankton abundance and dynamics in the open and interior ocean is still an unknown field. The knowledge of gelatinous zooplankton distribution is especially challenging, because this type of plankton has a very fragile structure and cannot be ...
