Melting snow and glacier ice in the Himalaya forms an important source of water for people downstream. Incoming longwave radiation (LW in ) is an important energy source for melt, but there are only few measurements of LW in at high elevation. For the modelling of snow and glacier melt, the LW in is therefore often represented by parameterizations that were originally developed for lower elevation environments. With LW in meas...

Summary We report on a genomic and functional analysis of a novel marine siphovirus, the Vibrio phage SIO‐2. This phage is lytic for related Vibrio species of great ecological interest including the broadly antagonistic bacterium Vibrio sp. SWAT3 as well as notable members of the Harveyi clade ( V. harveyi ATTC BAA‐1116 and V. campbellii ATCC 25920). Vibrio phage SIO‐2 has a circularly permuted genome of 80 598 bp, which displ...

Summary Eukaryotic molecular diversity within the picoplanktonic size‐fraction has primarily been studied in marine surface waters. Here, the vertical distribution of picoeukaryotic diversity was investigated in the Sargasso Sea from euphotic to abyssal waters, using size‐fractionated samples ( N ovel A lveolate groups I and II (NAI and NAII), or the novel Ma rine St ramenopiles (MAST). However, some deep‐sea NAII formed disti...

Pulsed field gel electrophoresis (PFGE) was used to determine the size distributions of virus‐like DNA in seawater from diverse environments (Arctic Ocean, Ross Sea, coastal Pacific Ocean, and northern Adriatic Sea). Changes in DNA banding patterns indicated that shifts in the viral assemblage composition occurred on the order of #2 d during an intense dinoflagellate bloom in coastal Pacific waters. Different DNA banding patte...
