Study of Seasonal Heat, Salt and Particulate Matter Transport in Thermaikos Gulf during 1997 - 1998

Previous studies have investigated the circulation and distribution of
suspended particulate matter in the wider area of Thermaikos Gulf. The aim
of this study is to supplement the existing knowledge of the area by studying
the transport of heat, salt and suspended particulate matter in the Thermaikos
Gulf and towards the Sporades Basin, using hydrographic data and direct
current measurements for the first time.
The data come from four oceanographic cruises, which took place in the
wider area of Thermaikos Gulf in May 1997, July 1997, September 1998 and
February 1998. The method followed includes the use of four cross-sections
(A, B, C, D) on the study area and the calculation of the respective transports
on each cross-section. In D cross – section, the geostrophic method was also
used.
Due to the sparsity of data and based on the error calculation, the results
reliability is limited to cross-section B, during all the seasons, and to crosssection
C in May 1997 and July 1997. The range of heat transport values on the
Thermaikos Gulf ranges from TH ~ -0.4 ± 3.7 TW to TH ~ -17.3 ± 6 TW, of salt
transport from TS ~ -3.9 ± 24.9 × 108 kg/s to TS ~ -84 ± 33.5 × 108 kg/s, while
suspended particulate matter transport from TPMC ~ 0.3 ± 3.0 kg/s to TPMC ~ 43.3
± 27.1 kg/s.
Heat transport, salt transport and suspended particulate matter transport
are constantly changing depending on the prevailing conditions in the area.
This is due to the surface heating and cooling, river runoff and the intrusion
of Aegean waters onto the Thermaikos Gulf shelf. The values and direction of
transport for cross-sections C and D indicates that there is no significant heat,
salt and suspended particulate matter transport to the Sporades Basin and the
Aegean Sea. In addition, the comparison of the annual suspended particulate
matter transport through the cross-sections, with the average annual
particulate matter discharge of the rivers in the study area, indicates that the
suspended particulate matter stays in the Thermaikos Gulf seabed.
