New Publication: Mesopelagic Fish Traits
How are mesopelagic fish adapted to living in the mesopelagic zone? In a recent litterature review (Andresen et al. 2024), SUMMER researchers collected existing knowledge of the fishes traits, and their resulting role in [...]
How can carbon transport be studied with a camera?
Carbon, which is the building blocks of all living material - such as you and me, as well as fish and plankton in the sea, is continually being transported from the ocean surface into the [...]

New Publication! Trophic specialization structures the fish community in Bay of Biscay
In a recently published research paper, scientistis from Ifremer and La Rochelle University studied feeding strategies of fishes, all the way from the surface to the deepest depths in the Bay of Biscay. Fishes [...]

How does the size structure of squid and octopus impact top predators in the mesopelagic?
Changes in the size structure of mesopelagic cephalopods can impact the energy balance of top predators. Humans are modifying the structure and functioning of marine ecosystems worldwide, both directly through fishing and indirectly through [...]
Kids discover the magic of the mesopelagic world
Before the summer holidays, the children of the coastal villages of Mundaka and Ea (Biscay, Spain) had the opportunity to discover the creatures of the mesopelagic zone through a 3D video. The initiative was made [...]
Science and Art Join Forces to Give Voice to the Mesopelagic Zone
In an innovative crossover between art and science, artists Entangled Others and Daphne Xanthopoulou, together with oceanographer Joan Llort, have presented "SonarMies: Liquid Strata". This installation creatively and experimentally transforms scientific data, transporting visitors [...]

Investigating photophores of Mueller’s pearlside
A group of master students at the University of Bergen recently published their findings on "Investigating the number and colour of photophores of Maurolicus muelleri in two Norwegian fjords", as a paper in the student [...]
Mesopelagic Symposium finished!
The mesopelagic symposium is finished, and it was a great success! During February 14.-15., the Mesopelagic Symposium hosted by SUMMER and MEESO was held in Copenhagen, Denmark. The end of this symposium also marks [...]
Current Knowledge of Mesopelagic Fishes
Fishes inhabiting the mesopelagic zone probably account for the majority of the world's fish biomass. As a result they have recently attracted considerable attention within science, industry and media, especially since they are part [...]
Studying Mesopelagic Fish in Iceland
How did I, a west coast Canadian, end up studying mesopelagic fishes in Iceland through the SUMMER H2020 project? It was definitely not a trajectory I could have predicted two years ago. I moved [...]
SUMMER posters from the 56th European Marine Biology Symposium
From 4.-8. September the 56th European Marine Biology Symposium was held in Reykjavik, Iceland. Within the symposium, one session in particular dealt with mesopelagic organisms, in which our project was highly represented. Out of 5 [...]
Dive into the deep ocean in a submarine with our SUMMER VIRTUAL EXPERIENCE
With the aim of raising awareness of the mesopelagic zone and the species that inhabit it, the AZTI technology centre, coordinator of the SUMMER project, has created an immersive experience that can be carried [...]
New publication: Lipids in meso- and bathypelagic fishes from the North Atlantic Ocean
The diet and feeding behaviours of many deep-sea fish are poorly understood. In order to gain more knowledge about this, SUMMER researchers from DTU performed fatty acid trophic marker analysis of lanternfish and bristlemouths. What [...]
Micronekton Optical Profiler System (MOPS)
An important shortcoming of active flux estimations in the ocean is related to the assessment of mesopelagic fish biomass. The latter values could be an order of magnitude higher than fishes captured using trawls due [...]
