Triplicate functions
(Journal article; Peer reviewed, 2022)We define the class of triplicate functions as a generalization of 3-to-1 functions over \(\mathbb {F}_{2^{n}}\) for even values of n. We investigate the properties and behavior of triplicate functions, and of 3-to-1 among ... -
Triploid atlantic salmon (Salmo salar L.) postsmolts accumulate prevalence more slowly than diploid salmon following bath challenge with salmonid alphavirus subtype 3
(Peer reviewed; Journal article, 2017-04-12)Triploid Atlantic salmon (Salmo salar L.) may play an important role in the sustainable expansion of the Norwegian aquaculture industry. Therefore, the susceptibility of triploid salmon to common infections such as salmonid ... -
Triploid Atlantic salmon and triploid Atlantic salmon × brown trout hybrids have better freshwater and early seawater growth than diploid counterparts
(Journal article; Peer reviewed, 2021)The use of reproductively sterile triploid salmonids would enhance the environmental sustainability of the aquaculture industry by preventing genetic exchange between escapees and wild conspecifics. To this end, we assessed ... -
Triploid induction in Atlantic cod (Gadus morhua L.) by the use of different pressure levels
(Master thesis, 2011-10-31)In the present experiment, different levels of pressure were investigated to see if it was possible to induce triploidy at a lower pressure level than previously used for Atlantic cod (Gadus morhua). Newly fertilized eggs ... -
Triploidisering av Atlantisk torsk (Gadus morhua); effekt av varierende hydrostatisk trykk og trykktidspunkt på triploiditet, samt konsekvenser for utvikling.
(Master thesis, 2013-10-31)Flere av utfordringene i norsk torskeoppdrett, er direkte eller delvis knyttet opp mot fiskens kjønnsmodningsfase. Kjønnsmodning fører blant annet til redusert appetitt og vekt, dårligere filetkvalitet samt høyere dødelighet. ... -
Triploidy leads to a mismatch of smoltification biomarkers in the gill and differences in the optimal salinity for post-smolt growth in Atlantic salmon
(Journal article; Peer reviewed, 2022)Sterile triploid Atlantic salmon (Salmo salar) show inconsistent seawater grow-out, but the reason why remains unclear. The purpose of this study was to determine the salinity optima of triploid post-smolts. Diploids and ... -
Trivial gain of downscaling in future projections of higher trophic levels in the Nordic and Barents Seas
(Journal article; Peer reviewed, 2023)Downscaling physical forcing from global climate models is both time consuming and labor demanding and can delay or limit the physical forcing available for regional marine ecosystem modelers. Earlier studies have shown ... -
Trofiske interaksjoner mellom appendicularia (halesekkdyr) og marine virus – konsekvens for virus diversitet, spredning og persistens.
(Master thesis, 2018-09-01)The appendicularian Oikopleura dioica (Chordata:Tunicata) is a mesozooplanktonic marine organism that utilizes a gelatinous house to effectively trap microscopic particles from seawater. Earlier observations of the ... -
Trophic interactions and abiotic factors drive functional and phylogenetic structure of vertebrate herbivore communities across the Arctic tundra biome
(Peer reviewed; Journal article, 2019)Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions and interactions with other species. The evolutionary and colonisation histories of ... -
Trophic structure of mesopelagic species in the Northeast Atlantic Ocean based on stable isotopes of carbon and nitrogen
(Master thesis, 2021-09-03)The mesopelagic zone is one of the largest, yet among the least explored habitats of the planet. Possible estimates of fish living in this zone range from around 1 to 15 billon tones of biomass which is 10 to 15 times that ... -
The tropical Atlantic observing system
(Peer reviewed; Journal article, 2019-05-10)The tropical Atlantic is home to multiple coupled climate variations covering a wide range of timescales and impacting societally relevant phenomena such as continental rainfall, Atlantic hurricane activity, oceanic ... -
Tropical Atlantic variability: Observations and modeling
(Peer reviewed; Journal article, 2019-08-27)We review the state-of-the-art knowledge of Tropical Atlantic Variability (TAV). A well-developed observing system and sustained effort of the climate modeling community have improved our understanding of TAV. It is dominated ... -
Tropical Atmospheric Response of Atlantic Niños to Changes in the Ocean Background State
(Journal article; Peer reviewed, 2023)Since the 1970s, Atlantic Niños during boreal summer have been linked to Pacific La Niñas the following winter. Earlier studies have explained the appearance of the Atlantic-Pacific teleconnection with changing Atlantic ... -

Tsunami risk communication and management: Contemporary gaps and challenges
(Journal article; Peer reviewed, 2022)Very large tsunamis are associated with low probabilities of occurrence. In many parts of the world, these events have usually occurred in a distant time in the past. As a result, there is low risk perception and a lack ... -
