This session was no. 15 of the YOUMARES 8 conference. It does not have a corresponding proceedings article.
15.1 Call for Abstracts
The Marine Sciences are a vast and divers field of research
and barely any conference is able to represent all topics with
a separate session. The Open Session aims to summarize
contributions of young marine scientists from all research
fields which do not feel to fit into one of the other sessions.

Full depth wintertime CTD transect data, spanning an
8 year period (2006–2013) and acquired along the
53°N–55°N and 54.5°N–56°N lines are assessed in relation
to inter-annual variability of Subarctic Intermediate Water
(SAIW), Mediterranean Outflow Water (MOW) and
Labrador Sea Water (LSW) water masses in the southern
entrance of Rockall Trough. The region is one of significant
mesoscale variability, where mixing between SAIW and
MOW upper intermediate water masses hinders interannual variability quantifications. Water column structure
and water masses present in the vicinity of the hydrographic
transect are examined by property-property diagrams,
where temperature and salinity, as well as potential vorticity are used as water masses tracers. Freshening of the
upper and intermediate water column south of 55°N in the
Rockall Trough region during 2012 and 2013 is observed.
General increase in wintertime salinity, 2009 onwards, is
detected close to Porcupine Bank continental margin at the
MOW depth range (1000 m), which could be representative
of a westward extension of the MOW salinity plume into
the northeast North Atlantic. At lower intermediate depths,
800–1500 m, cabbeling could be a potential mechanism for
inter-annual water masses modifications. Following a deep
(1250 dbar isobar) convection event in the Labrador Sea in
the early 2000s, strong signals of LSW at depths below
1500 m were detected in 2006, peaking in 2009.
Consideration is given to geostrophic current velocities and
volume transports. Geostrophic current velocities calculations, based on mean temperature-salinity relationships
derived dynamic height, appear reasonable, allowing for
preliminary regional volume transport estimates. The
southern Rockall Trough is uniquely positioned on the
boundary between the Subpolar and Subtropical Gyres in
the northeast North Atlantic, making the region a key area
of inter-gyre exchange. Therefore, existing hydrographic
data from the region could provide some support to the
recently suggested north-eastward expansion of the
Subpolar Gyre.

Halacarid mites are relatively small benthic animals, the
adult body length is less than 1 mm. Little is known about the
halacarid species in Turkey. This study focused on biodiversity and distribution of halacarid species which were collected in Antalya. For this purpose, samples were collected
from 10 stations between September and October 2015August, September and October 2016 along West Coast of
Antalya (Lara-Kalkan). In this study, a total of 714 individuals belonging to 16 genus, 37 species were determined.
According to the species numbers, Copidognathus ranked
first with 10 species. Copidognathus was respectively followed by Agauopsis, Rhombognathus with 5 species, by
Acaromantis, Agaue, Scaptognathus, Simognathus with 2
species, by Acarochelopodia, Actacarus, Anomalohalacarus,
Atelopsalis, Halacaropsis, Halacarus, Lohmannella,
Maracarus and Thalassarachna with 1 species. In summary,
this study has contributed to an understanding of the halacarid diversity and ecology of halacarid species in Antalya. In
addition, a check-list of the halacarid species that have been
reported from the coasts of Turkey to date is provided.
