Will you be working this year on a book or article that's going to need #maps? Let me help! I draw custom maps for a living!

I draw each map by hand, to my clients' specifications, & each is unique. You can find out more on my website:

surprisedeelmaps.com

Here's some recent examples of my work:
A Surprised Eel Map showing South America, with all of the countries named and the borders done in a light grey so that they are visible, but not obvious. The map shows the Amazon River, as well as the Rio de la Plata, the Parana River, and the Tiete River. The most salient part of the map is a series of large dark colored arrows, labeled "Flying Rivers." Each arrow is numbered, and has a shadow below it to suggest that it is floating above the map. The first arrow begins in the Atlantic ocean and goes west over the continent. The next turns back at the Andes, and then the last few split off of that into three different arrows that wind their way southeastward. There are lines showing evaporation in the atlantic, rain and evaporation over the Amazon, and lines showing rain the souther part of the continent. There is a key which reads: Life of a Flying River 1.Equatorial water evaporates off the ocean and is carried westward by trade winds 2. Cycles of evapotranspiration over the rainforest lead to emergence of an atmospheric ("flying") river 3. Colliding with the Andes, the flying river turns southward while feeding the headwaters of the Amazon basin 4. Continuing southeast, flying rivers carry accumulated water to distant parts of the continent via rainfall A black and white map showing a city plan for ancient Mycenae. Art. A greyscale map of southern Africa showing different biomes. The map map key indicates 7 different biomes: Succulent Karoo; Fynbos; Albany Thicket; India Ocean Coastal Belt; Mixed Woodland; Grassland; Nama-Karoo; and Kalahari Savanna. Each is represented on the may by a different shade of grey, with areas of more rainfall being darker, and areas of less rainfall being lighter. Several of the rivers are labeled, as is the Indian Ocean. Map of the globe, with Europe in the center. The map mostly does not show Oceania. The map is colored to look like an old-timey parchment maps. There are 15 drawings of various cultural artifacts on the map, each inside a black circle with an arrow pointing to the artifact's location in the world. A map title, written on what looks like torn parchment, reads, "Some Places and Treasures, Section 3: 1300 - 1500" There is a red dragon in the water. I've shown him before, so I'll share his alt-text again: A red sea serpent with little wings or fins. He might be a stupid dragon. His long, long tail curves several times before vanishing into the water behind him. You can't tell where in the world we are, as there are no landmarks. The serprent's tongue is yellow, like he's just popped a banana slug into his mouth. His expression kinda looks that way, too. His eyes are wide and his maw is open in something that looks like surprise. Like someone just pinched his butt in the middle of his quarterly earnings presentation. His name is Speril, and he is an only child

Glaciers are interseason water reservoirs. They accumulate water from snowfall and discharge it through melting, sustaining major rivers, even if there was a drought that year. But with ongoing droughts, glacier volume loss threatens those rivers. 🧪

Summary of changes in precipitation, air temperature, glacier volume and glacier runoff during the Chilean megadrought and the projected 10-year duration end-of-century (after 2075) megadroughts under RCP scenarios 2.6 and 8.5. Changes in precipitation, air temperature and glacier runoff are relative to the reference period (2000-2009, REF). Changes in total ice volume are relative to their initial values (year 2000). Given the projected increases in air temperature, we also anticipate an increase of potential evapotranspiration in downstream areas.

One of the important differences on the Front Range between December 2021 and today is the dryness that allowed for the Marshall Fire to take off. 30-day SPEI was extreme in 2021, while snow 2 weeks ago left fuels in a less receptive state. PSPS and lessons learned in 2021 likely helping out too.
A large area of SPEI values below -2.5 was in place along and east of the Front Range on December 26 2021, due to a dry and warm December in the region. SPEI accounts for precipitation and evapotranspiration. The most recent 30-day SPEI is much less dry than in 2021 though still in the dry category in Denver and the foothills. It’s been warm lately but remnant moisture from snow on December 3rd is likely still playing a role.

Hydrology Paper of the Day @foresttherotten.bsky.social on a forest in the Central Siberian boreal zone of China and evapotranspiration partitioning: how environmental factors cause evaporation to be of greater magnitude than other components, and application of the uWUE method for partitioning.

In China's boreal forests, a new study reveals evaporation's dominant role in evapotranspiration, highlighting the need for better water management strategies！🌲

The term 'Hydrogeology' was first coined by the naturalist Jean-Baptiste Lamarck in 1802 (Neven Kresic, Hydrogeology 101).

When you first come in contact with hydrogeology, a lot of terms sound unfamiliar. Every day I'll post 1 term definition for everyone with an interest in groundwater 💧👀.
Hydrogeology terms, definitions, filtration, groundwater recharge, groundwater discharge, evapotranspiration, unsaturated, vadose, phreatic layer, aquifer, flow, hydrologic cycle, hydrology.
