ABSTRACT We present the first draft whole-genome sequence for the Parmales (Bolidophyceae, Heterokonta), a picoplanktonic sister group of diatoms, using a Triparma laevis f. inornata strain that was isolated from the Oyashio region in the western North Pacific Ocean.

<p>The water quality parameters at 23 observation points in Weda Bay were collected using the Sea-Bird's Conductivity Temperature and Depth (CTD) 911 and Dissolved Oxygen (DO) meter ARO-USB 66 during Weda Expedition in 13 – 23 March 2013 (transition monsoon) with research vessel Baruna Jaya VII. The main goal of this research was to identify characteristics of water masses in Weda Bay. The results showed that the thickness of mixed layer in Weda Bay was about 40 m with the average levels of temperature, salinity, and oxygen at about 29.2 °C, 34.0, and 7.0 mg/L, respectively. Within thermocline layers, it was observed that there was the water type of Southern Subtropical Lower Water (SSLW) identified by the presence of salinity maximum above 35.0 occupied between 25.7 and 24.5 sigma-theta (16,2 °C &lt; &lt; 20,5 °C). Furthermore, there were oxygen homogenous layers at 5.1 mg/L situated at between 26 and 24.7 sigma-theta (15°C &lt; &lt; 20°C). In addition, oxygen inversion was found at 0.15 mg/L in the layer of between 26.8 and 26.0 sigma-theta (10°C &lt; &lt; 15°C). In the intermediate layer (&gt;500 m), the temperature and salinity tended to be constant at 7.8 °C and 34.7, controlled by the sill separating Halmahera sea and Western North Pacific Ocean (WNPO). These water mass characteristics revealed the strong influences from WNPO to Weda Bay. The water, driven by Indonesian throughflow (ITF), flowed into Halmahera Sea before turned into Weda Bay.</p><p>Keywords: temperature, salinity, oxygen, SSLW, Weda bay</p>
