title: Mesozooplankton adundance during Akademik Kovalevsky cruise AK7/5, Part II

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 0.145 mm. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-500 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.

description: Samples from 2 l of sea water were size fractionated by filtration through polycarbonate Millipore filters with pores 0.2 ?m, 1.2 ?m, and 3.0 ?m. The filters were kept deep frozen and analyzed according to Holm-Hansen et al. (Holm-Hansen, O., Lorenzen, C.J., Holmes, R.W., Strickland, J.D.H. 1965. Fluorometric determination of chlorophyll.

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 125 µm. Additionally, the JUDAY oceanic model JOM with 300 µm mesh size and 80 cm ring diameter was used.

description: 10-30 ml subsamples were concentrated on 25 mm black polycarbonate filters (0.6 µm for NF, 0.2 µm for B), stained with DAPI for 10 min and filtered. NF were counted using UV and blue excitation and enumerated. Heterotrophic B were counted using UV excitation. NF were classified in size categories and biovolume was calculated. NF abundance data were converted into C biomass using 220 fgC µm**-3. Bact abund data were converted into C biomass using 20 fgC cell**-1. BP C was estimated by the 3H-leucine approach according to Kirchman et al. (1986) and Kirchman D.L., 1993. Leucine incorporation as a measure of biomass production by heterotrophic bacteria. In: Kemp P.F. et al. (eds), 1993. Handbook of methods in aquatic microbial ecology. Lewis Publishers, Ann Arbor, 509-512). At each depth duplicate samples and a control one were incubated with 1 nM L-[4,5 3H]-leucine (specific activity 128 Ci/mmol) and 18 nM non-radioactive leucine. Samples were incubated in the dark at in situ temperature.

title: Mesozooplankton biomass during Professor Vodyanitskiy cruise PV18, Part II

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 125 µm. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through depths with the temperature gradient maximum (from 10-40 down to 50-100 m) and closed at the upper depth level. Integrated hauls (0-100 m) were also taken. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.

Replaced pump diaphragm of T300 CO and performed MPC. Replaced T204 NOx and Ozone instrument S.No 51 with T204 S.No 71 on 02/08/2017 due to noisy trace of Ozone and performed MPC.Issues: There was difficulty in determining the orientation of the 3D-sonic due to the surrounding infrastructure and nearby high tension electrical power lines. Final orientation was verified by comparison with wind direction data from the Australian Bureau of Meteorology, Sydney Olympic Park AWS site (station number 066212, GPS 33.8338, 151.0718). The average difference in measured wind direction to Olympic Park AWS was -27 23 (1 s.d., N=1036, Wind speed &gt; 1m/s), and 27 degrees has been added to the recorded wind directions
