  <dc:description>&lt;p&gt;&lt;span&gt;Precise point positioning (PPP) of ships using Global Navigation Satellite System (GNSS) data reveals the precise movements of marine vessels. This method may quantify anomalies in sea surface height with implications for oceanographic monitoring, exploration, and tsunami warning. The GNSS PPP data from the&amp;nbsp;&lt;/span&gt;&lt;i&gt;R/V Sikuliaq&lt;/i&gt;&lt;span&gt;, a research ship of the University of Alaska Fairbanks, were processed to detect a small local tsunami generated by the Lowell Point landslide, which occurred near Seward, Alaska, on 8 May 2022 (UTC). The GNSS receiver aboard the&amp;nbsp;&lt;/span&gt;&lt;i&gt;R/V Sikuliaq&lt;/i&gt;&lt;span&gt;&amp;nbsp;recorded the waves generated by the landslide, with a maximum wave amplitude of 6&amp;nbsp;cm and wave periods between 40 and 50&amp;nbsp;s. These results are consistent with simulations of the landslide event.&lt;/span&gt;&lt;/p&gt;</dc:description>
