Scientist which had two diamond markers, was the Russian

Scientist know that the floating aggregates must have some sort of role in the Arctic ecosystem. What was that role? That’s what scientist have been trying to figure out. Scientist already know how vital ice algae are to its ecosystem. They also know that the algal blooms can cause positive or negative effects. While not a new phenomenon, as there have been sightings in the past, there has been little data about the aggregates. Scientist wanted to know, just how important were the ice-algal aggregates during the melting season?Purpose: A previously stated, there is little data on the ice-algal aggregates. That was until the late summer of 2012. Two research cruises encountered large quantity of the buoyant aggregates during their trip in the Eastern Central Arctic. They were able to sampled and quantified the abundance, biomass, and production of the buoyant aggregates. The first figure shows the records of each research cruise that observe the ice-algal aggregates. The first recorded cruise was the Centre for Ice, Climate and Ecosystem, (ICE 12 for short) with the RV Lance, labeled ICE 2012. The ICE 12 is a national competence center for ice and climate research and environmental regions. The second cruise, which had two markers, was the IceArc expedition ARK-XXVII/3 with the RV Polarstern, labeled IceArc 2012. Third cruise, which had two diamond markers, was the Russian North Pole drift station NP-23, labeled as NP-23 1977. The final marker was the Fram Expedition from 1893-1896, though it is labeled as Fram 1894, since that was when the ice-algal aggregates were first spotted. The scale on the graph represents the depth in meters, ranging from 500 meters to 4500 meters. The depth of the water is represented in a blue scale colour, white being the shallowest and dark blue being the deepest. The broken line represents the ice edge at the end of July 2012.Three drift ice stations were also situated over the deep Arctic basin for the study areas. The first was occupied from July 26 to August 3 2012 during the ICE 12 cruise. It was located at 82.5° N, 21° E, initially supposed to be north of Svalbard. The two shorter drift ice stations were occupied from 9 to 11 and 14 to 16 August respectively during the IceArc expedition. The coordinates were 82° N, 78° E for station Ice1 and 84° N, 78° E for station Ice 2 (Assmay et al 2012).
