The dominant chlorophyll-a absorbs <a href="https://ecoevo.social/tags/light" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>light</span></a> in the violet-blue (430nm) and red (660nm) wavelengths, but not green, which is why <a href="https://ecoevo.social/tags/algae" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>algae</span></a> is green. Phycocyanin, an accessory <a href="https://ecoevo.social/tags/pigment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pigment</span></a> in <a href="https://ecoevo.social/tags/cyanobacteria" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cyanobacteria</span></a>, absorbs in those green wavelengths, so is blue in colour. This is why we can determine algae types from space.<br><a href="https://scitechdaily.com/new-research-suggests-earths-first-oceans-werent-blue-they-were-green/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">scitechdaily.com/new-research-</span><span class="invisible">suggests-earths-first-oceans-werent-blue-they-were-green/</span></a><br><a href="https://ecoevo.social/tags/Science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Science</span></a> <a href="https://ecoevo.social/tags/satellites" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>satellites</span></a> <a href="https://ecoevo.social/tags/oceans" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>oceans</span></a></p>
