ollowing the first set of field trips conducted by each of the par cipa ng countries in this year’s NANO Southeast Asia project, a second set of fieldtrips has been conducted to complete the field sampling work. The previous issue of NANO News (issue 6) included a report on the ac vi es conducted earlier this year by NANO alumni and associates in Thailand, Vietnam and the Philippines. The second set of fieldtrips corresponded with the wet season in Thailand, and the dry season in Vietnam. Tthe fieldwork from the Philippines group led by Joseph Palermo had already been completed earlier this year and summarised in the last NANO news. 2nd field observa ons in Cam Ranh Bay and Nha Trang Bay, Vietnam: The survey was carried out on 13 – 14 May 2014 for Nha Trang sta ons and 17 – 18 May 2014 for Cam Ranh sta ons. Weather and sea condi ons were good but there were some problems with the equipment, therefore this trip took more me than the last one. For 11 sta ons at Nha Trang Bay, the field campaign con nued from 6 am to 6 pm for two days with 9 researchers (8 from Ins tute of Oceanography and 1 from Ho Chi Minh City Ins tute of Physics). Water sampling at river mouths and gates of wastewater discharges were collected the day a er finishing the trip in Nha Trang bay. In Cam Ranh Bay, water sampling was carried out for 8 sta ons and 4 wastewater discharge sta ons by using a local fishing boat from 5 am to 8 pm. This took longer than in the Nha Trang bay. Physical parameters were measured by using a CTD and a current meter. Water samples in the bays were collected at surface and bo om layers and stored at 4oC in dark container for the analysis of nutrients, TSS and Chlorophyll-a in the laboratory. All samples were analysed within one week a er the field trips. Light profiles were also measured by using a PRR2600. In addi on, other parameters including Fluorescent-chlorophyll-a profiles, marine op cs and primary produc on under the VAST project (VAST-DLT.01/13-14) were also executed. Although manpower was limited and the equipment had some problems (the op cal depth of PRR2600 was not opera onal), the field observa on finished as expected.
