I’m using right away the coffee mag that I bought at Trident Cafe in Boulder, CO. www.tridentcafe.com

This is so cool to me because the top of “trident” like a fork is very similar to a Japanese Kanji, 山, which means a mountain. I appreciate this realization.

Trident cafe is must-visit cafe!

Today is the monthly monitoring of Lake Kasumigaura. It’s pretty nice weather.

Zooplankton team! It’s wonderful folks helping each other and fixing together if someone hits a wall. This pic was a dinner at Tea House, an iconic restaurant of Boulder, CO. Thank you everyone and @cu-esiil.bsky.social kind support!

Just touched down at Tokyo Airport. At the Denver airport, 2hrs after boarding on time, all passengers had to get off the plane due to mechanical issues. It was my first time getting a meal voucher. After grabbing a coffee for 1h, I boarded again. I’m happy I made it back safely.

If you visit Boulder, CO, you should stop by Piece Love and Chocolate.
It’s so nice atmosphere and many delicious chocolates!

I grabbed a hot coco with marshmallow. It was sooooo nice! I also got some dark chocolates for a gift.

We are a member of FreshwaterH2O of @cu-esiil.bsky.social. We made the projects forward through team building, working together, and many discussions. We sometimes create dataset, analyze data, discuss the results, go hiking, and grab chocolate. This week was so productive!

It’s time to leave for Denver, Colorado, to join the zooplankton workshop funded by ESIIL @cu-esiil.bsky.social.

Final day of the Sarufutsu fish adventure. We finally say goodbye to salmon carcass and rivers.

Beautiful meandering streams with colored leaves! I love it. It was raining, but the sun broke through for a moment.

My first sampling experience this year in mountain lakes was tough but magnificent 🤩 thanks to the team, Javi Sánchez Hernández @ignasiarranz.bsky.social @guillegargomez.bsky.social @biodiversosurjc.bsky.social @iicg-urjc.bsky.social

I'm going to visit Boulder, Colorado, again to join the freshwater zooplankton workshop. Honestly, I'm nervous as always, because English is a big wall to me. I'm not good at listening/speaking. But, I'm really excited to talk about science and receive many feedback and advice, which make me growth.

This is the iconic ‘Tower of the Sun,’ designed by artist Taro Okamoto for Expo 1970 in Japan. It still stands today, and you can even go inside. Did you know that? Inside, you’ll find the ‘Tree of Life.’
