For a long time, the only way to collect the data required for studying the deep ocean was by navigating the freezing waters of the north Atlantic in manned research vessels. These days many researchers opt to utilize Argo floats.
Argo floats resemble meter long yellow syringes which autonomously drift with ocean currents. Towards the end of their drifting cycle the floats dive to their maximum depth (2000 m) then ascends, taking consistent measurements of temperature and salinity along the way. Once the float resurfaces it transmits the collected data to satellites. The satellites repeat this submerging and resurfacing cycle several times, then forward the data to the national Argo data centers. This raw data is collected and processed before Yashayaev acquires it for subsequent analysis.
These Argo floats help provide a snapshot in time and are able to simultaneously massively increase monitoring efforts, and decrease manned field effort to paint the best picture of the Labrador Sea’s process, dynamics, water mass structure, variability and climate change. According to Yashayaev “The Argo program revolutionized the way we see the ocean – from once in a while sampling opportunity to year-round observation.”
Once data from the Argo floats have been received and gone through initial processing it is time to visualize the findings and let the ocean speak for itself. This is when Golden Software’s software packages come into play. Yashayaev’s preferred data visualization tool for single variable functions is Grapher. For multivariable functions he prefers Surfer due to its ability to process and map randomly scattered data. With Grapher he can display time series and vertical profiles of various variables all in one plot. These combined plots have a consistent, clean look across all the axes. Whereas other software either doesn’t have the option to include multiple variables in one plot, or doesn’t let you customize it to the point that the final product is publication quality.
Yashayaev finds that Grapher offers a perfect balance of options. One can either make a quick and simple figure, or if desired can customize every single element of the plot to a precise point.
He compares this level of customization to a painter on canvas:
“…it’s similar to an artist choosing the exact brush size, stroke, and color to elevate his painting.”
Furthermore, according to Yashayaev:
“…what you see on the screen is exactly how it is printed. Other graphing programs are not always this way, the export may differ from the original plot presented on your monitor and can vary with different monitor size and resolution. With Grapher these small imperfections (upon export) are practically nonexistent.”
For maps that are included in his publications Yashayaev finds he can create journal quality graphics using only Surfer. The options available meet his color scale, transparency, and labeling needs without having to bring the maps into a third-party image editing software.
As a final cherry on top, Igor feels confident in his choice of Golden Software because of how helpful and responsive the customer support team is. Over the years he has communicated with dozens of Support Agents and Product Managers. He finds the technical support always offers solutions within 24 working hours of him reaching out. Plus, if he makes a feature request a Product Manager directly follows up with him once it is added. Overall, this leads to him feeling as if his requests are truly heard and he is part of the development team.
His research is truly a collaborative matter between him and the Golden Software team, as any painter would attribute his work to the maker of his paint brush.
