We join the 27th IAHR Int. Symp. on Ice in Gdánsk, Poland, this week. @rmfredensborg presented sea ice ridge statistics in Barents Sea and Fram Strait from #ICESat-2! 🛰️
Interesting discussions on deformed ice, offshore ice-ocean-structure, applications of remote sensing! ⛴️🧊❄️

Replying to @HSkourup
@hskourup and @rmfredensborg at ESA-ESRIN for the #St3TART-FO kick-off meeting! Exited to continue on the procedures for establishing fiducial reference measurements (#FRMs) for #Sentinel-3 Altimetry Cryo products 🛰, to support validation of altimetry sea ice variables ❄️🧊

🆕 Big #Cryo2ice news! 🆕 CryoSat and ICESat2 data give us a sneak peak of what to expect from the upcoming CRISTAL mission.
Better understanding of snow thickness on ice, one of the biggest sources of uncertainty in ice thickness estimates.

Having trouble with that manuscript?😕😣📝 The ups-and-downs of scientific writing can be challenging for new PhD students (and researchers too) and are often only learned through experience. This is a great thread outlining common stumbling blocks and ways to work around them!
As an academic writing coach, here are the 9 mistakes I see PhD and grad students make when writing scientific papers.
A thread 🧵 as long tweet:
#1: Thinking it’s laziness when you are procrastinating on your paper
🦥 Most PhD students procrastinate writing their paper (aka have ‘blank page syndrome’) not because they are lazy but because they don’t know where to start tackling this overwhelming project.
—
#2: Starting to write your paper by “writing”
📋 The first step of writing a paper isn’t to type out full sentences. It’s more efficient to first develop your story and create a good outline so writing just becomes filling in the gaps.
—
#3: Trying to make your sentences perfect in your first draft
🤓 If you keep deleting what you have written, you won’t get a lot of text on the page. The goal isn’t to get every sentence, every word right from the beginning but to refine your paper through editing.
—
#4: Accepting edits from your PI without understanding them
🖍️ Critical feedback from your supervisor can feel discouraging but it really is an opportunity to learn. So, ask for the reasons of edits and rewrites so you can refine your writing skills one iterations at a time.
—
#5: Trying to tell a story in your paper without knowing that really means
🎬 Ever been instructed by your supervisor to “tell a story” in your paper without getting a definition on what that means? Ask them for feedback on your story board so you are on the same page!
—
#6: Underestimating how long writing tasks take
⏱️ As a rule of thumb, quadruple the time you think you need to get any writing-related task done. And start using a time tracker so you have data on how much time each step takes going forward.
—
#7: Asking for feedback too late
💬 It’s a waste of time for your supervisor to correct a fully completed draft as the first touch point. Agree on the story and outline of each section before your start writing.
—
#8: Thinking your supervisor has the writing process figured out
🤫 If you feel like your PI isn’t giving away their secrets, it’s likely because they just don’t know how to teach you! The truth is, few researchers rely on an efficient process to write a successful paper.
—
#9: Not asking for writing training
💰 If you feel under-skilled at writing, ask your PI, department or grad school for funding to take a scientific writing course. Many universities have funding available for professional development, you just have to make the ask!
—
TL; DR: 9 mistakes I see PhD students make when writing their scientific paper
#1: Thinking it’s laziness when you are procrastinating
#2: Starting to write your paper by “writing”
#3: Trying to make your sentences perfect in your first draft
#4: Accepting edits from your PI without understanding them
#5: Trying to tell a story in your paper without knowing that really means
#6: Underestimating how long writing tasks taks

🙌 A huge thank you to our quality working group community for their continuous support for @ESA_EO’s ice mission
🗓️From 26-28 September, 40 of us gathered in person and online for our ninth meeting
💬Over three fruitful days, we discussed the quality of the CryoSat Ocean Baseline D 🌊
📉 📈 These meetings ensure CryoSat continues to accurately monitor changes to global ice and sea levels
