End of 1-year survey in the Bach Dang Estuary (initiated 16 October 2009)
Along the navigation channel (i.e. stations 4 to 28), 9 stations were subject to CTD and LISST profiles every 2 neap tides (i.e. every 28 days). Among those, 5 intermediate stations were sampled systematically at 1.5 m depth for determination of nutrients, DOC, POC, PON, TEP, Chl.a, bacterial abundance, production and diversity, viruses abundance and diversity.

The project VITEL (Vietnam Remote Sensing) has been funded by CNES (PI S. Ouillon, IRD UMR LEGOS, co-applicant Torreton JP, 32 K € Year 1) and aims to develop bio-optical algorithms valid for coastal waters in the Tonkin Gulf. Its implementation will deepen Vietnam-France cooperation in physical oceanography already initiated within the framework of HAIPHONG, and will allowing a synergy with biological and biogeochemical approaches developed within activities of UMR 5119 team. The first measurement campaign will be conducted in the first quarter of 2011. This project will be implemented in partnership with the IMER (VAST) and Xavier Mari and JP Torréton (UMR 5119 Vietnam).

The project ‘Study of the structure and fluctuations of planktonic viruses and bacterial communities in the coastal environment of Northern Vietnam to help sustainable development of marine ecosystems’ proposed by Chu Van Thuoc was accepted for funding by the Vietnam Academy of Science (20,000 USD for 2010-2011). This project also involving 5 UMR5119 ECOLAG scientists (Y Bettarel, C Bouvier, T Bouvier, X Mari & JP Torréton) will provide the opportunity to reinforce the on site training activity of Vietnamese partners from the VAST (IMER & IBT) in the fields of bacterial and virus diversity initiated during the HAIPHONG project.

Submission of the ALGECO project (P.I. Sylvain Ouillon, LEGOS) to the PNTS (French National Programme on Spatial Remote Sensing). The objective of the project is to define and validate new coastal bio-optical algorithms of the broadest possible application (i.e. for very wide ranges of turbidity and contents in Chl.a and CDOM). Campaigns of optical measurements and companion variables will be done in Hai Phong Bay and in the coastal sea area. This project, which feasibility was tested during the HAIPHONG 2 campaign will involve, among others, IMER (Chu VT, Do TB, Vu DV) and IRD participants (S Ouillon, J-P Lefebvre, E Rochelle-Newall, X Mari, J-P Torréton) from the HAIPHONG project.

An International Project for Scientific Cooperation (PICS) was submitted for funding to CNRS (PI T Bouvier, UMR5119). This cooperation project is based on the HAIPHONG project and aims at developing a Vietnamese-French partnership on bacterioplankton diversity. This project was prepared in cooperation between ECOLAG (UMR5119), the Institute of Marine Environment and Resources (IMER, Vietnamese Academy of Science and Technology, VAST Haiphong) and the Institute of Biotechnology (IBT, VAST, Hanoi).

March 10-23, 2009
The HAIPHONG 2 campaign (dry season) took place from 10 to 23 March 2009. The joint Vietnamese (12 participants) - French (11 participants) team worked at IMER Haiphong
A meteorological station (wind speed and direction, air temperature, photosynthetically active radiations) was set up during the period of the campaign.
Field measurements and sampling were done using a rented tourist boat.
Temporal surveys (every 3h during 24h cycles) were done at 2 river locations (Bach Dang, Cam) and at station 4 (confluence Bach Dang and Cam Rivers) during spring tides. Parameters recorded along vertical profiles across river transects included flow measurements (ADCP), temperature, salinity, turbidity and in vivo chlorophyll fluorescence (CTD), and particle size (LISST). Surface and bottom water samples were collected every 3h for suspended particulate matter, nutrient, contaminants, bacterial production and abundance, zooplankton and phytoplankton.
Spatial surveys were done along 3 coast - sea transects during neap tides (total 35 samplings at both surface and bottom of the water column). In addition to CTD and LISST vertical profiles, samples were collected for chemistry (nutrients, organic matter, particulate matter, and contaminants), biogeochemistry (particle aggregation experiments) and biology (zooplankton, phytoplankton, bacterioplankton, virioplankton).
The ROSALIE project aiming at determining the influence of salinity on bacterioplankton and virioplankton diversity (P.I. Y Bettarel) took place at IMER during the HAIPHONG 2 campaign.
Analyses are presently under process at IMER (Haiphong), IRD Noumea (New Caledonia), LEGOS (Toulouse), ECOLAG (Montpellier) and IPREM (Pau).
