This voyage crossed almost 10,000 km (6,000 miles) from the Atacama trench, passing through the Desventuradas Islands, visiting several seamounts along the Nazca undersea ridge, the islet of Salas y Gómez and the mythical island of Rapa Nui, passing along the back of the Pacific Basin through the Austral Islands, to finally dock after 34 days in the port of Papeete, Tahiti.[/et_pb_text][/et_pb_column][et_pb_column type=”2_5″ _builder_version=”3.23.3″][et_pb_image src=”https://moevarua.com/wp-content/uploads/2019/06/Mana-Ilustracion-del-Monte-seamount-illustration.png” _builder_version=”3.23.3″ custom_margin=”||-1px|||”][/et_pb_image][et_pb_text _builder_version=”3.23.3″ text_font=”||||||||” text_text_color=”#000000″ text_font_size=”15px” background_color=”#ffffff”]

However, just as in the deserts there are oases, in this enormous marine area that is marked by low productivity, there are zones in which the animals gather.  The oceanic islands and the seamounts make favorable environments for the presence of a wide range of living creatures with vary particular characteristics.   Given their isolation, the flora and fauna of these areas tend to be endemic, that is to say, to consist of species that are only found in that specific part of the planet.[/et_pb_text][/et_pb_column][et_pb_column type=”2_5″ _builder_version=”3.23.3″][et_pb_image src=”https://moevarua.com/wp-content/uploads/2019/06/JAVIER1.jpg” _builder_version=”3.23.3″ custom_margin=”||-2px|||”][/et_pb_image][et_pb_text _builder_version=”3.23.3″ text_font=”||||||||” text_text_color=”#000000″ text_font_size=”15px” background_color=”#ffffff”]

As an example, the majority of the animals observed and collected on the “Mana” seamount correspond to the first registry in the Chilean archive of marine biodiversity, or even species new to science.   Given the volume of samples and data, analysis is going to take some time and the results will be published next year at the earliest.  However, this information will contribute to the protection of the emblematic ecosystems that were visited, especially those of the Nazca-Desventuradas and Motu Motiro Hiva marine parks.[/et_pb_text][/et_pb_column][/et_pb_row][et_pb_row _builder_version=”3.23.3″ border_width_all=”2px” border_color_all=”#ffffff” border_style_all=”dashed”][et_pb_column type=”1_2″ _builder_version=”3.23.3″][et_pb_image src=”https://moevarua.com/wp-content/uploads/2019/06/Una-desconocida-especie-de-erizo-de-mar-del-monte-Mana-An-unknown-species-of-sea-urchin-from-the-Mana-seamount.-.jpg” _builder_version=”3.23.3″][/et_pb_image][et_pb_text _builder_version=”3.23.3″ text_font=”||||||||” text_text_color=”#ffffff” text_font_size=”15px”]

This moai will stay on board, occupying a privileged spot in the main meeting room, as it accompanies the ship and its crew through the oceans of the world.[/et_pb_text][/et_pb_column][et_pb_column type=”2_5″ _builder_version=”3.23.3″][et_pb_image src=”https://moevarua.com/wp-content/uploads/2019/06/Meliton-Heka-Tuki-Consejero-del-Mar-de-Councilor-of-the-Sea-from-Rapa-Nui.jpg” _builder_version=”3.23.3″][/et_pb_image][et_pb_text _builder_version=”3.23.3″ text_font=”||||||||” text_font_size=”15px” background_color=”#ffffff” custom_margin=”-82px|||||” custom_padding=”26px|||||”]
