An san McDougall da haɓaka, tare da David Jackett, wani tsari na ƙayyade saman yawa mara tsaka-tsaki. Waɗannan su ne saman da ke jujjuyawar teku - waɗanda faɗinsu ya kai kilomita 10-500 kuma suna ci gaba da wanzuwa tsawon watanni da yawa - gaurayawa. Yawan haɗuwa mai rikitarwa a cikin teku ya ninka sau miliyan goma da ƙarfi a saman "yawa" fiye da yadda yake a kan waɗannan saman.

Ya kasance shugaban ƙungiyar International Association for the International Science of the Oceans (IAPSO)  ta ƙungiyar International Union of Geodesy and Geophysics daga 2019-2023 kuma ya kasance tsohon shugaban ƙasa na 2023-2027. Ya jagoranci ƙungiyar aiki ta SCOR da IAPSO waɗanda suka ƙirƙiro ma'anonin ƙasa da ƙasa na halayen thermodynamic na ruwan teku, iska mai ɗanshi, da kankara ( TEOS-10, Thermodynamic Equation of Seawater - 2010), waɗanda Hukumar Kula da Teku ta Duniya ta amince da su a 2009.
