The pathfinder is designed to measure the attenuation length of the water and perform a long-term assessment of the optical background at the future P-ONE site. After 2 years of continuous operation, measurements from STRAW show an optical attenuation length of about 28 m at <jats:inline-formula><jats:alternatives><jats:tex-math>$$450\,\mathrm {nm}$$</jats:tex-math><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mn>450</mml:mn> <mml:mspace /> <mml:mi>nm</mml:mi> </mml:mrow> </mml:math></jats:alternatives></jats:inline-formula>. Additionally, the data allow a study of the ambient undersea background. The overall optical environment reported here is comparable to other deep-water neutrino telescopes and qualifies the site for the deployment of P-ONE.</jats:p>
