🔍 What you're seeing... Scientists aboard an Antarctic research vessel prepare a CTD rosette sampler for deployment into the icy waters of the Ross Sea. This instrument captures water samples at different depths and measures temperature, salinity, and depth—essential for tracking ocean circulation, ice melt, and climate-driven changes. The Ross Sea is one of the coldest and most pristine regions on the planet. Data from here is vital to understanding global sea level rise and strengthening earl
