From December 22 to Christmas Eve on December 24th, we had clear skies and collected 50 hours of data. Working with our PI, we also did training sessions on the principles of how different components of the system work. On the iron lidar, we identified ways to correct the laser spectra on the transmitter side, and improve the collection efficiency on the receiver side. These improvements doubled the signal we received! <\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"625\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2020\/01\/dinner-1024x625.png\" alt=\"\" class=\"wp-image-154\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2020\/01\/dinner-1024x625.png 1024w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2020\/01\/dinner-300x183.png 300w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2020\/01\/dinner-768x469.png 768w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2020\/01\/dinner.png 1171w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Christmas Eve Dinner in the Galley.

These are interesting atmospheric phenomena that we study, but collecting data in the summertime is a little challenging because of background noise from the sun. The sun will stay up until our next sunset on February 21st. Improvements we made during this session will improve our data quality for the next run. <\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"600\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team2-2.png\" alt=\"\" data-id=\"136\" data-full-url=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team2-2.png\" data-link=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/?attachment_id=136#main\" class=\"wp-image-136\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team2-2.png 550w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team2-2-275x300.png 275w\" sizes=\"auto, (max-width: 550px) 100vw, 550px\" \/><figcaption class=\"blocks-gallery-item__caption\">Our full team in the Lidar Lab!<\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"908\" height=\"839\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team.png\" alt=\"\" data-id=\"132\" data-link=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/?attachment_id=132#main\" class=\"wp-image-132\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team.png 908w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team-300x277.png 300w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/team-768x710.png 768w\" sizes=\"auto, (max-width: 908px) 100vw, 908px\" \/><figcaption class=\"blocks-gallery-item__caption\">Our day team at Hut Point, after seeing penguins<\/figcaption><\/figure><\/li><\/ul><\/figure>\n\n\n\n<p>On Christmas day, skies were cloudy so our team took some time to enjoy the holiday. We went to Hut Point, where the Discovery Hut that Scott&#8217;s team built in 1902 still stands preserved in ice. We toured inside the hut and found supplies from the early 1900s still there- including seal meat, onions, dog biscuits for the sled dogs, and oatmeal. There is also the remains of an early science experiment measuring gravity near the pole (gravity is slightly different at the equator vs. the poles, and early explorers measured this with remarkable accuracy). Elaine Hood from USAP gave a brief history lesson on the different missions that used the hut, and there are many incredible stories. <\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"227\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/IMG_5046-1024x227.jpg\" alt=\"\" class=\"wp-image-129\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/IMG_5046-1024x227.jpg 1024w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/IMG_5046-300x66.jpg 300w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/IMG_5046-768x170.jpg 768w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/IMG_5046-1536x340.jpg 1536w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/IMG_5046-2048x453.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Enjoying the view outside of Discovery Hut<\/figcaption><\/figure><\/div>\n\n\n\n<figure class=\"wp-block-gallery columns-3 is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0273-1024x682.jpg\" alt=\"\" data-id=\"138\" data-link=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/?attachment_id=138#main\" class=\"wp-image-138\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0273-1024x682.jpg 1024w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0273-300x200.jpg 300w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0273-768x512.jpg 768w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0273-1536x1023.jpg 1536w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0273.jpg 1732w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"blocks-gallery-item__caption\">One of many supplies left in the hut<\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0300-1024x682.jpg\" alt=\"\" data-id=\"139\" data-link=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/?attachment_id=139#main\" class=\"wp-image-139\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0300-1024x682.jpg 1024w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0300-300x200.jpg 300w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0300-768x512.jpg 768w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0300-1536x1023.jpg 1536w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/DSC_0300.jpg 1732w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"blocks-gallery-item__caption\">Gravity science experiment<\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"467\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/hut-1024x467.png\" alt=\"\" data-id=\"140\" data-full-url=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/hut.png\" data-link=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/?attachment_id=140#main\" class=\"wp-image-140\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/hut-1024x467.png 1024w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/hut-300x137.png 300w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/hut-768x350.png 768w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2019\/12\/hut.png 1214w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"blocks-gallery-item__caption\">Discovery Hut<\/figcaption><\/figure><\/li><\/ul><\/figure>\n\n\n\n<p>While outside Discovery Hut, we saw our first Adelie penguins!
